I have about 200 pound to upgrade my computer

An i am happy with my i5 2500k and 8 gb ram

I currently have an xfx 7850 core edition and realise that i cannot upgrade much with 200 pounds

So i thought i would crossfire but realise my XFX 550W Pro Series Core 80+ Bronze psu wouldnt be powerful enough so i was wondering what psu i should buy ( im guessing 750 w ) an also if one of the cards overheated from how close they are how i could fix that?

Thank you

Ideally, you'd sell the 7850 you have and just buy a higher-end single card like a 7950 or 670. You wouldn't need a PSU upgrade and you wouldn't have all the issues that come with Crossfire/SLI. As for how close the cards would be, it depends on the expansion slot layout of your motherboard.

Otherwise, a quality 650w unit should be good for two overclocked and overvolted 7850s.
