So I'm trying to budget build a gaming computer, so far I basically have two options here. My main goal is to spend under 650 dollars. I came here to ask this community which would be better, from a gaming standpoint. I will be playing games as old as World of Warcraft and Half Life to as new as the upcoming Guild wars 2, crysis 2, and other upcoming 2011 games.
So anyways, lets cut to the chase (assuming they both cost right around 650, there is no cheaper option).
Option #2 would be the better choice in my opinion, but upgrade to an Athlon X3. Building an AM3 machine today will give you the option of a CPU upgrade down the road (Phenom II X6 for example).
Regarding Option #1... There is no need for tripple channel memory. LGA1156 is dual channel just the same as AM3 (install in pairs). Also, consider building a LGA1155 machine (Sandy Bridge) instead of LGA1156 if you are sticking with Intel.
