I plan on upgrading my PCs GPU in the near future, my price range is about 110$, i was wondering if two 640s would outperform one 7770?

If your looking for the absolute best bang/buck 2 gtx 640s are better than a 7770. Be aware sli does not work in everything or scale well in everything.

I would go with the 640s, people will say best single gpu performance and crossfire later.

It's up to you.

640s don't sli... Minimum of 650 ti boost for sli in the 600 series.

I am sure you mean GT640 which does not support SLI
Only the GTX 650 or higher I think

So you are better off with one 7770
