I decided on all the items I want in my new PC build, but I'm a little confused and basically overwhelmed looking into graphics cards. So I've come to the pros for some advice. Here's what I have so far: Motherboard: AsRock P55 Pro CPU: Intel Core i5 750 Memory: Corsair 2x2GB PC3-12800 DDR3 (CMX4GX3M2A1600C9) HardDrive: Western Digital 1TB 7200rpm (WD1001FALS) PowerSupply: Corsair 750w (CMPSU-750TX) Case: Antec Nine Hundred Two Ultimate Gaming Case Now I'm confused between nVidia GTX 260 or Radeon HD 5770. Which one will work best with my set up? Does it matter if I'm using Intel and not AMD? I'm trying to get the best under $250.00. I was looking at the XFX GeForce GTX260 896MB GDDR3 PCI Express (GX260XADJC), but then the Radeon is running Direct X 11 and might be better in the long run. For that I was looking at either: Sapphire Radeon HD 5770 1GB DDR5 or XFX HD 5570 1GB DDR5 (HD-577x-ZNFC) , but then I saw this one and couldn't even determine what the difference is the XFX HD 5570 (HD-577A-ZNDC) Please help me get the best graphics card out of these. OH! I almost forgot what I'm using the PC for, well my son is a constant WOW player and I will be downloading, converting, and burning movies. Thanks in advance.
