In terms of overall gaming performance, the graphical capabilities of the Intel HD i5 660 are marginally better than the Nvidia GeForce 6800 XT.

The HD i5 660 was released over three years more recently than the GeForce 6800 XT, and so the HD i5 660 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 XT when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce 6800 XT has 256 MB video memory, but the HD i5 660 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 6800 XT has 12 Shader Processing Units but the HD i5 660 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i5 660 requires 73 Watts to run but there is no entry for the GeForce 6800 XT.
