I am getting an epox 87ka and a 1.2ghz 266fsb athlon a thermaltake volcano II heatsink, and 256mb of PC2100 ram. My current mobo and 700mhz cpu died so instead of spending cash on a new vid card I just ordered the above. My question is since I am stuck with a tnt2 will overclocking achieve anything? would overclocking make a diff even if I had a geforce 3? I am also not so sure about my case, its a new generic full tower with four fans apart from the cpu fan and power supply, at the moment I have no way of checking temperatures.
