Thanks guys for your feedback its very much appreciated,
is this the one you are suggesting,
XFX Radeon HD 5750 Graphics adapter - 1 GB - GDDR5 SDRAM
and do you know why the other cards have more ram ie 2gig and the one you suggest has 1gig is that not important sorry to have to ask more but that part is confusing to me i thought the more ram the better, i guess not a!
PS the card you guys suggest looks impressive and is in my price bracket
Thank you very much rocky41 and mohsentux for your help
