Question please...

Yes it is. The 8600 is more than twice what the 8500 is and then some.

Depends on the models involved

What the heck?? Are u completely insane??

The 8600 GT is more than twice as good as the 8500 GT!

Whats with u lately?

No wait!

Get the 8800 GTS 320!

Do you even bother to learn about the various models out there?

If you get a GF8500GT with GOOD MEMORY then it will overclock alot, and make it worth the money. Otherwise like I said in general the GF8600GT is worth the extra money you pay. The Gainward GF8500GT beats most GF8600GT cards at stock speed, because it's clocked at 600/700(1400) versus 540/667(1330) and not SP bound and OCs very well, so like I said it depends on which one you're talking about and the price. There are also of course some GF8600GTs with faster cores and better memory for the price, but if you clock the GF8500GT beyond it beats the stock GF8600GT despite the SP difference and for the money can be worth it, so I don't see what's so difficult about what I said. Remember it's also value.

In general the GF8600GT is worth the money, because it has a better starting point even for overclocking, like I said.

What's wrong with you period !?!
