Upgrading a new GPU

[The Trickstarrr]

So, currently, I have GeForce GT 520, bought for 50 quid from a maplins, but even though i thought it looked brand new, turns out its not such a good gaming graphics card. So i was thinking of buying a new card, that will play most games in HD full resolution and top spec... such as crysis. I plan linking an Acer Gr235H via HDMI, and a LG W2243, via DVI or VGA. My Motherboard is a ASUS M5A78L-M with 8gb of DDR3 Ram and an AMD Quad Core CPU. Can someone find me a decent one, price of up to about 800 pounds? Thanks

This costs around 162 Pounds and is a pretty decent card for the price. You can play Crysis 2 at Max settings too.
nVIDIA GeForce GTX 560 Ti

But it requires a 500 W power supply and two 6-Pin connectors.
