How much better is nvidia geforce GTS450 then nvidia geforce 9800 GX2 video card?

The 9800 GX2 is more powerful, but lacks the dx11 that the GTS450 has.|||I would suggest to buy EVGA GeForce GTS450 FPB 1 GB GDDR5 PCI-Express 2.0 Graphics Card

GeForce GTS 450 with 822 MHz core clock

PCI Express 2.0

1024 MB 128-bit 0.5ns GDDR5 memory

3608 MHz memory clock and 1645 MHz shader clock

NVIDIA 2-way SLI ready
