In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8600 GT 512MB GDDR3 are significantly better than the Intel HD i5 661.

The HD i5 661 was released over a year more recently than the 8600 GT, and so the HD i5 661 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the 8600 GT.

The 8600 GT has 512 MB video memory, but the HD i5 661 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The 8600 GT has 32 Shader Processing Units but the HD i5 661 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 8600 GT 512MB GDDR3 requires 46 Watts to run and the HD i5 661 requires 87 Watts. We would recommend a PSU with at least 350 Watts for the 8600 GT. The HD i5 661 requires 41 Watts more than the 8600 GT to run. The difference is significant enough that the HD i5 661 may have a slight adverse affect on your yearly electricity bills in comparison to the 8600 GT.

GPU Mini Review

Mini ReviewGeForce 8600 GT 512MB GDDR3 is one of the many variants of the fast-middle-class GeForce 8600 GT.
On this version, the GPU is equipped with 512MB of standard GDDR3. The architecture allows the use of 512MB, since the GPU's processing power is strong enough and the memory controller is up for the task of processing 512MB. Therefore, the performance is superior to the 256MB version and any other version of DDR2, including 1GB.
However, and due to its architecture limitations, modern demanding games will require reduced settings, even if they don't require more than 512MB of video ram. Very Demanding games like Metro 2033 are only playable at the lowest settings.
Intel HD i5 661 is a specific version of Intel GMA graphics that is built into the Intel Core i5 661 processor. This can handle most of the latest games like Call of Duty: Modern Warfare 3, Batman: Arkham City and The Elder Scrolls V: Skyrim on the lowest settings in a pretty good frame rate. Perfect fit for a non-hardcore gamer.
