what kind of performance does the 7950GTX offer over the 7900GS?

Im asking because my Dell Inspiron E1705 laptop has the 7900GS now,and was considering trying to find the 7950GTX that would fit in it. The Ebay prices are outragous for it tho.

Would this upgrade be worth it at all?

The GTX kills it - probably 50-70% faster in most apps. However, I'd be pretty surprised if you can find a 7950GTX that fits yours. Notebook GPUs aren't as standardized as desktop ones.

Don't forget that 7950GTX will produce more heat than the 7900GS. So if there is insufficient cooling, it can actually kill your entire laptop.

Not sure of these form factors any more, but if mobile cards still follow the MXM profile, then the 7900G would most likely be a Type I or II. The 7950GTX will definitely be a Type III MXM profile; too big to fit in a Type I or Type II bay.

Of course if the Dell Inspiron comes standard with a Type III MXM bay, then you should have no problems fitting in a 7950GTX.

That leaves cooling as the next priority.

Google for ya ;) 

The ebay pages also list the laptops that the Dell version of the 7950 GTX is compatible with.

It works,it uses 2 heatpipes instead of one and requires a little case modding appearently,but it does seem to fit none the less.
