Ram question: ddr2 4gb at 667mhz or ddr2 2gb at 800mhz?

A friend of mine is upgrading his computer. He has an XFX 680i lt sli motherboard. What is better in RAM: 2gb at 800mhz or 4gb at 667mhz? He has XP. Also, should he get ECC ram, buffered ram, or normal ram? He wants to play games such as WoW, DIablo II, and maybe Crysis.

Four. You definitely notice a 100% difference in amount over 25% in memory speed - which isn't really noticeable anyway.

That mainboard uses normal DDR2 memory.

definitely the 4 gigs. the mhz difference shouldnt make much of a difference, and the added 2 gigs will definitely make up for it anyway. think of it like this: with the 2, you can move data faster but have less space to move it to, so it would have to move data in and out more often. the four gig though, moves data a little bit slower but has a LOT more space to hold data. in my eyes, the 4 gig would definitely be the better choice
