for one thing, you dont need that V8 heat sink unless you live in the desert, or overclock your processor, and second, ditch that sound card, its a waste, most new Mobos have great sound already.
AMD is what i would think you would want for a good gaming biuld.
Phenom II 955 BE 180$
good choice
M4a78T-E Mobo 130$
good choice
DDR3 OCZ Gold 1600 96$
good choice
5850 DX11 1GB DDR5 260$
very good choice
550W Corsair PSU 80$, 60 after Mail in Rebate.
pretty sure the Antec EarthWatts got good reviews, but CORSAIR is probably the most reliable PSUs you can get, personally I only use OCZ or CORSAIR
Antec 900 100$
Antec makes quality cases.
Logitec Wave Keyboard/mouse 85$ ( have it, love it)
i still don't see non-gamers should be spending this much on keyboards good mouse though
Plextor Dvd Drive 45$
Western Digital Caviar Blue AAKS 640GB 70$ ( i honestly dont see the use for 1TB but thats me
i say go 1TB, the spinpoint f3s are great and hard drives arent that expensive, its like $10 for 360GB more space
Hanns G 28in LCD Monitor 310$
$110 extra for 3 inches more? your choice, Hanns-G makes good monitors though
I dont think i missed anything.
All that for roughly 1350$
with Windows 7
64 Bit 190$ Windows 7 for tech-builders is only $109 OEM or $190 for ultimate. I'll post link after the quote
comes to 1546$.
Has a better Screen, ton better video card, this PC will last you for a good amount of years to come.
