I just upgraded my gaming rig. New Gigabyte AMD based 990 chipset w/ DDR3, Xfire or SLI support, AM3+ motherboard. Installed 16GB G. Skill high performance DDR3 memory. New Phenom II X4 965BE cpu. All I can say is wow. I kept my "old" 5870 as it still kicks some major ass. This thing flies.....I'm really pleased with the performance. And this Gigabyte board is amazing. Great BIOS setup. I'm lovin' it!
