Is the 9800 GX2 Worth it!?

It's less money ($275, or $245 ar) than 4870 ($280) and gtx280 ($420) while outperforming both.

Your motherboard does not support sli, and p45 bottlenecks 4000s in crossfire.

So you're limited to single card. 4870x2 is the fastest single card on market, above 9800gx2, although it cost over twice as much.

My opinion is to simply go with a Radeon 4870 it can be found for around the same price as the 9800gx2 and I believe offer comparable performance. the 9800x2 would be more powerful in some games but it relies on sli profiles to exist for that game. I know that my experience with the 7950gx2 was less that favorable because of this but sli has improved since then. I still recommend going with a radeon 4870. You could even crossfire them if you wanted more performance your psu should be powerful enough

If you can get a 9800GX2 cheap, then go for it. It is in the same class as a GTX260/280 and the 4870. Some games will run better on one card than another. Unless you have a favorite game you should be happy with a 9800GX2 in general.

In all the games i play. COD4, Crysis, Valve engine etc. The GX2 comes out on top!

Thanks for the response guys. Ill overclock that sucker and get free performance
