Okay so here's my situation now. I've pretty much decided on this for now:
Q6600 (I'll most likely overclock this to 3 GHz)
Gigabyte GA-EP45-UD3P
2 gigs of ram
Windows XP
Now the hard part is deciding on the graphics card. The mobo supports crossfire. So I've been going back and forth between the gtx 260, gtx 280, and the 4870 (1 gb and 512). My goal really is to play games (stuff like DMC4, Starcraft 2, Street Fighter 4, Tomb Raider: Underworld... not Crysis or Far Cry 2) in 1920x1080 at 60 fps (with most detail type stuff at max... 2xAA or 4xAA, probably nothing higher). Obviously I could just go nuts and get a gtx 280, but I'm actually leaning towards sticking with a 4870 right now. This way, if I need the power later to meet my 1080p 60 fps goal, I could throw in another 4870 for crossfire.
The problem with that is that I'd have to decide on whether or not I get the 1 gig or 512 MB. Once again, I'm playing at 1080p and will not play at anything higher (by the time I do I'll get a new system). Then couple that in with the possibility that I might toss in another 4870 card in later... and you are now where I'm at!
So what are your guys' thoughts?
Also, I've never used SLI or Crossfire before, but do you need the *exact* (manufacturer included) same cards in for them to really be optimal (or work for that matter)?
Thanks for any input.
