Hi there, Thinking about purchasing 1 of the PowerColor ATI Radeon X1800 XT 512MB cards as an upgrade to my x800 xt pe as id like to run all my games at full detail at the high resolution i use (1680x1050) which my current card cant quite hack. Is this a worthy upgrade and will i see the desired extra power im looking for? Rest of my system spec is A64 3500+, 2gb Corsair which im hoping isnt too much of a bottleneck. Opinions? Many thanks.
