Best video card for PCIE x16?

My mobo box says my slot is a PCI express x16. I currently have a ati radeon x800 and i wish to upgrade. what is the best video card i can have for those specs?



PS. i have a 460 W power supply, will i need to get a more powerful one?|||Well that power supply is probably enough for most cards with the exception of the dual cards (HD 3870x2 and 9800GX2).



The very best card available is probably the GeForce 9800GTX at this time. That said, I don't recommend it, as it is about 5% faster than cards $100 cheaper.



A card that is right arround the performance of the 9800GTX is the GeForce 8800 GTS 512mb 256-bit (G92) core:

I think you will have enough power unless the rest of your system is really a power hungry monster.



For a jump down of about 15% in performance, the GeForce 9600 GT 512mb 256-bit. This card uses way less power is is also much cheaper ($125):

Even less expensive than that (with again low power requirements) is the Radeon HD 3850 with free steam black box for $110: Maybe 10% slower than the 9600GT

If you really need to cheap out, the 8800GS is similar to the HD 3850, but has no blackbox, this takes a lil more power, but still not that much:

If all that is too expensive for you, you can drop to an 8600GT OC which is like 50% of the HD 3850:

Just to give you an idea of performance, the HD 3850 will max Unreal 3 games @ like 30-50fps ave. Personally I would check if you've got enough power for the 8800 GTS 512mb with 100% load and 20% aging http://extreme.outervision.com/psucalcul…



If you can't use that, get the 9600GT. If you want the black box, get the 3850. Otherwise, cheap out progressively as described if you're short on cash.
