change the gfx card if u want to play better games go with the 4870 / gtx 275 or 4890 dont cost much more

If youre not gaming even a 4850 is surely overkill.
I will only be playing the odd game such as football manager or cod 4... soo not really sure what would be the best gpu to get... i was thinking that if i get the 4850 for now.. then when the new ati cards are realsed i could save up and upgrade to one of them... this setup is pretty much my whole budget,
In that case get the 4770. Performance similar to the 4850, but much more efficient and cheap.
