If you won't overclock the Celeron E1200, it is definitely a bottleneck for 9600GT. If you overclock the Celeron E1200 to 3.2GHZ or higher, it won't be a bottleneck for 9600GT.

The small 512K L2 cache isn't that great for gaming. It hampers gaming performance fairly badly, even with hefty overclocking. XBit benchmarks a 3.4Ghz Celeron on par with a 2Mb L2 cache E4600 at 2.4Ghz:

If this is a new build, spring a little more for the E2160 and overclock, but if this is an OEM purchased computer you were thinking of adding a 9600GT too, the performance increase will be tangible, albeit castrated, and your money may or may not be better spent elsewhere.

At stock speeds it would be a massive bottleneck. Due to the small cache and low clockspeeds, a stock Celeron E1200 is a terrible gaming CPU - even overclocked to 3GHz barely moves it into 'passable' territory.

I'd agree with JuiceJones, spend a little more on a E2160, its only about $20 more, but the larger cache makes all the difference in gaming performance.
