I was thinking that because of the future thing.. I mean I went Quadcore to be future proof on my games and such, and doing the same for the GPU would only make sense, sure it won't be the "best gaming rig" out there right now, since I'll only have a 4890 in there alone.. but hey.. never was one to be #1 at my PC stuff.
Even if it won't Cross Fire up to a ... 4900 series or whatever they go to.... another 4890 in there would surely be cheaper and worth the upgrade then.... so yea.. 4890 might be the way I go.
Hows the cooling on the XFX one? Newegg.com - XFX HD-489A-ZDFC Radeon HD 4890 1GB 256-bit DDR5 PCI Express 2.0 x16 HDCP Ready Video Card - Desktop Graphics / Video Cards
any problems with it?
OH and about that sound card....?
