I think I have narrowed it down to the 6800gs card; however what’s the difference between different manufactures cards? I am in the uk so if you can either suggest a manufacture to avoid or to aim for that would be great, or even if you think the 6800gs isn’t the card for me please suggest something that I can get in the UK for around about £150. Thanks. I have looked at www.dabs.co.uk and www.ebuyer.com
