sli or single gpu have £200 max

Hey

I have an I5 4670k , 8gb 2400mhz ram and Asus sli mobo powered by corsair 650 watt moduler psu. Just looking for a good gpu now. I want a gtx 770 but cannot afford it, so is there any sli mix that could compete or maybe a good card that I could buy now and pair later thanks

Can overclock to similar level as GTX 770. You should easily be able to get it past 1100Mhz on the core.
