I've got a couple of questions: With my vanilla 8600gts I got the result of 138690 on aquamark 3. I overclocked it to 773/1141 and the aquamark score went up to 144574. I don't have any games to test the difference visually. This pc is relatively new for me and on my previous P4 1.6Ghz I refrained from buying good-quality games because I knew that I'd end up disillusioned. However I wouldn't want to run an overclocked card if the overclock would be too minor in my case to make a difference in game-play. At the overclock, the gpu temperature went up to 61 degrees. Will the overclock be making a noticeable difference when within in a couple of days I'd be getting Oblivion or is the oc so minimal that it's not worth it? Another question - would you suggest that were I to keep the current oc on the gpu I should look for after-market cooling? I'd love to hear experiences from other 8600GTS users here. Any 8600GTS users there? Do you OC? How much? What cooling do you use? I also wanted to ask - since I'd be playing Oblivion soon do you think I'd be getting a better graphical performance with an overclocked card or is my card too 'mid-range' to benefit from significan result-producing overclocking and hence I shouldn't be bothering at all? As a final word, I have Windows XP but as soon as Vista is more stable and there are tempting DX10 games out there I'd be switching on to Vista and probably ditching my video card in favour of a high-end DX10 compatible one in the future. Now that it's too late I wish I had purchased the 8800 version, however I'm stuck for the time being and the only choice I got is to make the best out of my 8600GTS.
