Der er jo ikke så meget andet end 1 eller 2 GB og især ikke i den klasse han har lagt sig. Tjek evt disse pinball http://www.tweakup.dk/article/1051/dk/
the E4300 will get you from 1.8 to 2.4 on DDR2-533 RAM. The E6300 will get you from 1.86 to 1.86 on DDR2-533 RAM.
DDR2-667 will get you to 3.0GHZ on the E4300 DDR2-667 will get you to about 2.3GHZ on the E6300
DDR2-800 will likely be more than you can the E4300 push and may get you to about 3.2-3.4GHZ.
DDR2-800 will still really only get the E6300 to about 2.8GGZ which is still less than the E4300 on DDR-667.
DDR2-533 will not let you overclock any Core2Duo significantly except the E4300. The E4300 will yield a 33% overclock which is very nice but is far from pushing the limits of the E4300.
My personal preference with the E4300 would be for DDR2-667 since that takes the CPU to a comfortable 3.0Ghz. Going beyond this yields minimal performance differences that are really noticed but does involve more risks. Of course if you can get teh DDR2-800 for about the same as DDR2-667 go for the faster ram just for leeway.
The E6300 gets REALLY pricey when you need to start looking at DDR2-1000 to have it hit top speeds since DDR2-800 is not sufficient. This is why I tend to look at the Core2Duo options as sort of E4300, E6400, and E6600 as reasonable. The E6400 will let you push the CPU to the limit with DDR2-800.
Every Core2Duo is manufactured via the basic same process. Each CPU itself has the same clock potential. Whether its the E4300 or the E6800. There are some variances such as the default multiplier. default clock rates, and the amount of Cache on the CPU.
The E6600+ have 4mb on-board and working. The E6300-E6400 have 4mb on-board with 2mb disabled. The E4300 have 2mb on-board.
Let's start with Cache...... 4mb working is Good. Advantage E6600+ Now for the others......... 4mb w/2mb disabled means wasted heat/energy. Advantage E4300
Default Clock Speed...... Simply Put, the higher the default the better. This means the CPU you purchase has been tested at a higher rate. This does not increase the max CPU potential, but increases the chance that your CPU will get closer to the max potential since the CPU was likely tested at speeds at least slightly higher than the others.
The E4300/E6300 are tied here with only a 0.06 difference in default speeds. The E6400 gives a little boost here and is still a budget chip.
CPU Multiplier -
The E6800 Wins hands down here since you can set this up down as you like. All other C2Ds only support downward settings. the E4300 Wins among the rest because it has the highest starting value.
Price There are basically two categories here. The E4300<->E6400. There is about a $45-$50 Price difference here. The E6600s are about $150 more than the E4300s. Each step above the E6600 is quite expensive. --------------------------------------------------------------------------------- In your post you mostly mention the E4300 vs the E6300. The problem with the E6300 is that is only has disadvantages and no advanteges.
1) It's slightly more expensive. 2) It has disabled Cache which generates needless heat could add to cooling costs. 3) The rated speeds are the same so OCing the CPU itself has the same potential success rate. 4) Adjust the CPU multiplier of the E4300 to 8 and set the FSB to 533 and you have yourself an E6300 in performance. Any change you now make to either system will yield identical results. However, if you have OCing issues with your RAM, FSB, or other components on your FSB at high speeds you can choose to lower the FSB and raise the multiplier to 9 and get higher CPU speeds.
The next chip to consider in buying a C2D is the E6400. This chip is tested at 300Mhz more than the E4300. This means that it has greater chance of reaching the max C2D potential since it was tested at higher speeds. The cost is about $45 for this added benefit. For those who wish to push their systems to the limit of what C2D may be able to do, this is a good option for the price. For those who do not plan on pushing their systems to the max, it is likely not. The $45 could be better spent on a better GPU, PSU, Sound Card, etc.. etc....
The next chip is the E6600. This chip rings in at about $150 more than the E4300. The E6600 is the next class chips with 4mb of cache which is very nice. It is tested at 600Mhz above the E4300. This chip is even more likely to clock higher than the E4300. This chip will also beat all previous chips on a clock for clock basis due to the extra cache, though not significantly. The issue with this chip is the price and now fundamental decisions may need to be made depending on your budget and use of the PC. This money could move somebody from a 7600gt to one of the new 8800GPUs for $300 or from a lower end 8800GPU to a higher end 800GPU.
Since most posters are gamers and game performance is key, the $150 is normally better spend on GPU than CPU. If budget is not a constraint, then the E6600 is clearly the best choice as this is the 1st CPU to really differenciate itself from the E4300.
The CPUs above E6600 are really just for those with wads of cash. They are too expensive to recommend in any build based upon a budget. They are simply recommended if you can buy w/o much concern for cost. Clearly the higher the chip the better at this point.
So in summary, I can see no reason to ever really buy a E6300 over a E4300. The reason is not solely to save $10. It is simply a better CPU for overclockers. For those who do not OC, spend the extra $30 over the E6300 for the E6400.
And yes, there are many cases where a E4300 is a better chip for certain builds than the E6600. This is because of the simple fact there is a budget and the $150 difference could go to other pieces.
In regards to the Cooler, that is really pointless point. All of these chips will need coolers to reach the same speeds. The E4300 would actually need a less powerful cooler than any other chip due to less cache and less CPU heat as well as a potentially more conservative FSB which is going to reduce heat from other components as well.
Most of the OCing "issues" I have seen are due to folks not buying the correct components not the CPU itself. One chap bought a x975 Mobo that clearly was not designed for OCing since it did not even let you adjust the CPU multiplier. Missing basic Bios options is not a good sign. The other chap I recall had purchased DDR2-533 RAM. While it saved him money, he failed to grasp the rated speeds required to reach 3.0 and higher. It does not matter what CPU you buy if the components purchased with the CPU are not up to snuff. The nice thing about the E4300 is that it is more forgiving than the other CPUs in regards to that other stuff.
