It should work fine as it will draw all of its power from the pci slot..

 

[seanpr92]

also with the 770 ive done some research and found its a 2 slot does this mean it needs 2 pci-e or just one? bit confused as its my first gaming pc

 

[nate714]

it only plugs into one pci-e slot, but it takes up the physical space of two expansion slots.

 

[seanpr92]

so it should be able to fit a full sized desktop case ?

 

[ARICH5]

yes it will fit.

you do know you wont see a huge improvement over your 6670. youre maybe jumping one or 2 teirs in performance.

you have a decent cpu and ram. id say ya shoulda saved for at least a geforce 670 or a 7950

 

[seanpr92]

i could save i mean i can currently play AC3 in high everything without anti-aliasing

I think you should get maybe a step higher like the 7870 or the 7850. Or possibly you could wait for the next gen cards
