Ok here's my delima. I have the following POS: -Cooler Master case (older one, the one with the blue plexy glass door) -Enermax 450w PSU -ASUS P4T533-C/ 478 Intel 850E ATX Intel Motherboard -Intel Pentium 4 2.8 Northwood 2.8GHz Socket 478 Processor -ATI RADEON 9700 PRO 128MB 8X -ATI TV WONDER PCI -512mb RAMBUS pc1066 Samsung RAM I put it together in August 2002. It was all top notch back then and I had to preorder most of it. Now it's comparable to an intelevision (if you remember that). I want to build another pc but until all the new stuff comes out, I'm waiting. i.e. the ATI 3870 x2 cards. So until then I'm wondering what I can do to get a little more out of my current rig. It's all pretty much stock, everything is being run at current speeds. If I overclock and need to buy any heatsinks and stuff, I need to make sure that they are compatible with whatever I buy in the future (well not really since they are only like $50). On a follow up to that. Once the ATI x2 cards come out (assuming they perform well) I will be building a new system. For that I am wondering if anyone has any suggestions on the motherboard, what kinda pcu to use. I'm looking at a core 2 duo (it's outperforming amd right?). I've really fallen outta the loop on pc stuff lately. I've been soaking up all that this forum and other review forums have to offer though. Thanks guys. p.s. almost forgot, will overclocking my GPU and CPU actually help with anything since I only have 512 of RAM? pc1066 is impossible to get now so I can't upgrade any.
