Ok heres the situation, I have a stingy character who doesn't want to spend more than R1000 (thats roughly $120) on her setup. And even better if she can not spend anything at all! now she is running on an HP dc7100 2.8 P4 ht with a (please, brace yourselves, I nearly choked when I heard this) a PCI -as in not agp or pci-e- FX5200... now I told her that there is no way to actually upgrade this thing since the case is so small that nothing but her low profile FX5200 (which I had to hunt around for) will fit in her case. She just uses the machine for animation, rendering and occasional mild gaming, but she would like some extra performance. So I went to overclocking her GFX card. The dc7100 has surprisingly good cooling capabilities and I managed to clock it to get a score of about 116 on Video Card Stress Test (it previously did benched at 79). the problem is it doesnt overheat when I clock it higher (the gpu or memory) then it just goes slower. what is missing here?
