Alright, its upgrade time. I posted a thread earlier some months ago when I was aiming for a GTX465, but now the Nvidia Geforce GTX460 has come out and I am going to buy it. I don't really game, just sometimes, but I mostly use a flight simulator, some editing, and CAD (nothing to serious, google sketchup mostly). My 8800GTS 640MB, is still a monster but its starting to well...get outdated and can't handle some of the stuff I do anymore. Its time for it to retire. So my question was, I see two different GTX 460's, the 768MB and the 1GB version. The 1GB version is about $30+ more expensive if not more, so is the 1GB version that much better that its worth the price jump?, and what confuses me is that the 1GB version seemingly has a slower Core/Mem/Shader Clock than the 768MB version. Either way, the jump to the 460 will give me a huge performance jump, its probably three times as powerful and has DX11 which I am looking forward to and 3D. So any ideas as what the point of more memory but less Clocks is? And is the extra 256MB of on board ram justifiable especially for my needs? Thanks for any advice.
