I'm struggling to pick a graphics card, I know which one I want (GTX 760) but I don't know which vendor to buy from. Here's the top two that i've picked out:
Inno3D GeForce GTX 760 iChill HerculeZ 3000
Gigabyte GeForce GTX 760 WindForce
I've never actually heard of Inno3D, which is a bit offputting. Looking at images, it appears to be a 3slot card, which will limit your ability to do SLI. I'd say get the Gigabyte. Reliable, well known brand. The windforce cooler is known to be good and relatively quiet. It only takes 2 slots.
