I've decided to upgrade my graphics card since my current one is really old and I've wanted to have a card with hdmi output for quite sometime. I know the GT 640 2GB isn't supergreat but I only intend to use it for Guild Wars 2 and dual screen with my TV.
Would my motherboard be able to support the GT 640 even though it's PCI-E 1.1 ( I think) and would my CPU be able to support it aswell?
Because apparently this card is designed for PCI-E 3.0 and I've read that it's backwards compatible with 2.0 but I'm not sure about the 1.1 hence my question
So let's say then I would get this card instead Gigabyte GeForce GTX 650 1GB as you mentioned, would my CPU still actually handle that one without any bottleneck? and I'm unsure whether my PSU can support this too, cos i've read graphics card requires different amp currents and I couldn't find out how much this one needs but the psu requirement seems to be 400w atleast.
My psu has dual rails, 12v giving 20A each and max output 35A.
