do you have a budget?

Wouldn't bother with crossfire. As above, budget?

Hi,

Budget about £200 ideally (GTX760 is a little under this). However I don't want to spend £200 and then find I'm wanting to upgrade again within a year.

Also will i5 CPU become a possible bottle neck say for GTX760 or GTX770. I'm happy to upgrade in steps, would just like to know if I need to plan for CPU upgrade in a year say.

If thinking of GTX770 is 2GB ok or better to go for 4GB for future proofing (I know this is pushing the original budget)?

i5 wouldn't bottleneck the GTX 770. For gaming in 1 screen the 2gb version is fine.
