My first build

[Prototype]

I agree, if this is for gaming, you will need at least a 9600GT (about $130 or less). If you don't plan on overclocking your quad core cpu, what you have is fine. The 680i is a safe board to go with to avoid the chances of having video corruption like the 700i series.

Also, this RAM is cheaper and highly rated (more than your GeIL)
Newegg.com - G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory

didnt they release some new BIOS update and fixed some boards?

srub the gpu and get either a 9600gt or 8800gt
if you will be ocing get cruciall ballistix ram (tracers)

Crucial Ballistix are good again?

^the tracers have never been bad...it was only the normal crucial.

get a p35,p43,p45 mobo and a better vga. like a 8800gts g92

I'm just throwing in my 2 cents here, but I have an 8800gts 320 (not g92) and itll pretty much max any dx9 game at 1680x1050 and possibly higher. With that being said, there are definitely some better cards out now, but it sounds to me, that with a p45 mobo youre gonna want a pcie2.0 card, so i'd opt for the 8800gts g92 if i were you

^no cards out even use the maximum band availible so it wouldn't matter which card he bought.
