**The same Benchmark score after GPU upgrade????**

1 word.
Bottleneck.


8800GTS on my system gets about 2900
GTS 450 gets slightly above 5000 on my system
GTX 460 gets around 6700+ on my system


GTS 450 on my brother's Athlon II X2 bottlenecked system gets between 1900-2300.



While your performance in other games has increased, it's still not as good as if you had a more powerful system. A lot of games can be CPU bound.

And it's been shown in multiple articles that a PhenomX4 with the same GPU as a high end Core i7 will perform consistently and significantly less across the board. Though that doesn't mean it doesn't manage perfectly good framerates.


Also my system spec's for reference

Core i7 950@4.2Ghz
(No GPU ATM because dead 460)
G-skill 1333Mhz RAM@1600Mhz 8-8-8-24-1N
Corsair TX750
