k here is ur list revised and reasoning
unless of u already made up ur mind, i would suggest an AMD seeing as how ur getting a 7600GT im assuming you want it for gamng, so then definitely get an AMD 64 3700+ which is about $200
as for mobo the MSI K8n neo4-f or the DFI Lanparty UT Ultra-d, both of which are cheaper and the one of the best on the market. MSI-$70, DFI-$130 or something
ur ram choice is ok if ur not planning on overclocking. im not sure but if those sticks dont have heat spreaders then i wouldnt get them, i believe u can get a Patriot 2x1GB PC 3200 i think, its amazing ram and its about $160. its called Patriot Signature 2x1GB, it has heat spreaders which is very beneficial and is blue, just look for it on newegg.com
As for PSu u dont need OCZ PowerStream 520Watt with the parts ur buying. a system with Sli'd 7900GTXs require 550Watt and u could use a ANtec TruePowerII or SmartPower, i believe the smartpower is 450Watt and the TruePower 480watt or vice versa, both are more than enough for ur needs. and with all this you save a hefty amount of money, about 240-300 depending on which parts u pick.
Id rather buy corsair xms overclocking rather than any patriot but the corsair valueram is plenty good enough and is rock solid ram but not meant for overclocking.
The amd 939 chips are good chips for the money but since the conroe is coming out soon I would wait and buy an Intel conroe cpu. If you havnt heard yet, the conroe is a kickass processor that owns the fx-60 and fx-62 for less money, even if amd cuts the prices in half the conroe is still the better buy.. Nothing wrong with the socket 939 3700+ but 1. its not dual core 2. its considered older technology coming very shortly. 3. You can get the cheapest intel conroe for pretty cheap. 4.amd is slashing the prices on the socket 939 x2 dual core by 50%.. You are better off with an amd socket 939 x2 dual core than the regular 939 3700+...http://blogs.zdnet.c.../index.php?p=15
I would wait and get an intel conroe cpu the 2.40 ghz version is very good priced at around $315 and it still beats the fx-60 and fx-62 dual core. The 2.40ghz conroe still has the 4mb cache also.. The 2.67ghz conroe is around $529 but its still a pretty good deal. Overall the 2.40ghz conroe is the best deal for the speed, and will be the lowest priced chip for that much speed and again, it still beats an amd fx-60 and fx-62.
