I have just chosen all of the parts for my perfect computer (power + price), now I need to know if they all are compatible with each other.
Help is much appreciated.
Case: Very good
Motherboard: Excellent, but unnecessary. Just get the normal UD3R and DDR2 memory, you'll see no benefit with DDR3
CPU: Very good
Heatsink: Mediocre - use an Arctic Cooling Freezer 7 Pro instead - http://www.newegg.com/Product/Product.aspx?Item=N82E16835186134 Thermal compound: Excellent
Memory: Poor - Corsair is a good brand, but the C boards only have 2 slots, so you're limiting yourself to only 2GB of memory, which isn't always sufficient, and you have no option to upgrade at a later date, not to mention you're throwing money away using DDR3 instead of DDR2.
Motherboard URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128359 RAM URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16820145214 $194 for the pair, $149 after rebates. You've saved $12, got twice as much RAM, and the same performance.
PSU: Excellent
GPU: Excellet performer, hope you didn't pay over the odds for it, such cards are only really worth about $250 tops these days, and they usually sell for a lot more than that.
With the three modifications I have made, your system will definitely be comptible.
