Cheap monitor to run with a GTX 460?

Hey guys, I'm just wondering what is a good cheap monitor that can get maximum benefits out of a single GTX 460 card?

I used to have 2 7600GTs in slit and could run 1024 x 768 no problem. Whats the maximum resolution I could get out of this with an Athlon II x3 and the above card?

I could probably stretch to £150 but anything at all cheaper would be good.
I'm hoping to play games like Mafia 2, PES11, COD, Dead Space etc.

Thanks guys .

Is it the 1gb model?

Oh didn't realise there was a 1GB model, but it's going to be the 768mb.

Thanks.

Edit: I might look into getting a 1GB card now.
