Could I have some help in choosing a Graphics Card?

In terms of pricing how much would these components cost if they were to be bought seperately? Also can you say whether these are good for PC gaming?

NVIDIA GTS 250, would this be good for Dragon Age medium settings?

NVIDIA GeForce GT220, would this be good for Dragon Age medium settings?

GMA X4500, would this be good for Dragon Age, medium settings?

If not, what games would they be good for or if they'd surpass please say so. :)

Thanks.

First of all your not going to be doing any gaming on a GMA 4500.

The GTS 250 would be the best option. You can buy it on Newegg for ~$135.

The GT 220 is not a gamer card, more like an HTPC card. That can be had for ~$70.

The GTS 250 would be the most capable card out of the 3.Luminouslight

Would this Desktop be of a reasonable spec then?

Note that £480 is just around the $700 dollar mark.

Thanks guys, much appreciated :)

So would this Desktop spec be of a reasonable price and standard for PC Gaming?

Thats an excellent PC for that price.
