I'd like to get the best gfx card for under £100 thats suitable to my situation. I only have a 370W PSU, and at the moment have a cheap 3450, which unfortunately can't play cod4 at a decent enough frame rate on even a 1028 resolution. Can someone recommend a gfx card that i can get for £100 or less that would be able to run on a 370W PSU? Is this even possible, or should i just stick with the 3450 until i get the cash together to change the PSU as well!?
