I've had my eye on an GeForce GTX 660 2GB for quite some time.I have a standard Dell XPS 8500 right now and I'm planning on upgrading it sometime. Some concerns I have are if I will need modular power for this as well as if my computer will be able to handle this card? It currently has a 460W power supply, but some have told me I will need modular power in order to run this card. I am positive that it won't bottleneck considering I run an I7 processor right now. I could use another computer expert's opinion on if it would be able to work with this card! Thanks!
