Then I would go for a GTX 480 as that GPU can be found for around £200 such as the EVGA GTX 480. Since I'm from the US, I have not done much research on the prices from the UK, maybe some UK folks can give a better solution than mine.
With the GTX 480, you would be able to max out most games at 1920x1080 and your PSU is fine to handle the GTX 480.
its £190 pound so its a good price! Will this fit to my motherboard? ill get this pc mechanic to do the installing for me. i know its just plug in but i dunno if i need to install any other software bits and bobs.
Yes it will fit fine, you can do it your self and save money unless he is doing it for free. It's easy really, just use Driver Sweeper to uninstall the old AMD driver and then reboot computer, then install the latest Nvidia driver and you will be good to go.
I am just trying to find the absolute best performance per pound. Your suggestion is a very good card and I am sure the OP would be happy with it.
I understand that "x2"'s are not everyones cup of tea. I have a 4870x2 myself, but since I only have a 1680x1050 monitor it is an acceptable setup to me.
I have not had any problems with my card. and truthfully I would LOVE to buy the card I suggested if only my wife would allow it... And if you were to say, here have this GTX480 I would near pull your arm off in my hurry to snatch at it ;D.
haha, I feel ya, that's a good GPU that you posted. Nothing wrong with that GPU. Maybe you should buy a new pair of shoes or a purse for the wife and blackmail her in order for you to get the GPU you want, lol
