I have a question, If doom 3 limits the frame rate to 60 fps does this mean that it controls the GPU to only run at up to 60 fps? if this is the case then does that mean that a program could utilise that extra power in the GPU in anyway? or is it so specialised that it can only do exactly what is supposed to?
When to buy a new G card, well i think its best to buy the old best ones a couple of months after the new ones are out and just keep doing that when needed.
