Right now i have an Amd Phenom ii x4 955be, 4 gigs ddr2 ram, running 2 5770s. the question i have. im looking to upgrade. Should i upgrade the gpus to 2 6870s or upgrade my amd to an intel chip. I am looking at the i7 950, ASUS Sabertooth X58 Motherboard, and 4 gb 1333 ddr3 ram. i know the intel setup is a little more than the 2 6870s but im curious what would be the better upgrade. this rig is used 85% gaming 15% media. Thanks
