I really want to upgrade my GPU because it doesn't support multiple monitors and it's been pretty annoying to play everything on medium or even low. So my question is, would it be a waste of money to buy a GTX 660 because maybe my other components will bottleneck it? Also, is the card compatible with my current hardware. I have a 550W PSU and here are the PCI specifications of my MoBo:
1 x PCIe 2.0 x16 (blue)
1 x PCIe 2.0 x16 (x4 mode, black)
1 x PCIe 2.0 x1
1 x PCI
If you need any other information to help me out, please ask!
Also, i am sorry if this doesn't belong here, i don't know where else to ask.
