At 170 MHz the only performance gain was 1 FPS in the Quake 2 Crusher demo. I feel this is not a noticeable gain and is not worth the extra heat and other side effects of overclocking. Probably, my CPU is at its maxed out in what it can provide FPS wise and therefore would not allow a performance gain even if the clock speed was increased. You should always attempt to overclock your card and see if you get a performance gain that would justify overclocking. Unless you have a V2 SLI setup or a TNT this would be a definite plus to your system.
Most people always think that the most expensive components are the best - here they are wrong.
It's up to par with the G200. Now it is acceptable for cards as well as games not to support 32 bit rendering but in the near future, performance will be greatly hurt if this is not implemented. It is also possible to put this card in a new system later. If you built or had someone build a non-OEM system for you then this could go either way. But if you don't have a decent video card this is a good card for you as long as enough dinero for a better cad then you should go for it.
