New graphics card suggestions?

Hello in another thread I discovered that my current 8800gts has died. I would like to see what kind of upgrade recommendations you guys have. Thanks in advance and just ask if you need more info.

I play mostly World Of Warcraft and League Of Legends. I do play a myriad of other games but none of them are current gen. I would love to play current gen games but my budget is rather low 100$ max.

Specs
Gigabyte Technology Co. P35-DS3L
NVIDIA GeForce 8800 GTS
4gb gskill
Intel Core 2 Duo E6750
2000Mhz
Antec NeoPower 650 Blue 650W ATX12V / EPS12V SLI Certified CrossFire Ready Modular Active PFC Power Supply

6750 or 5750.
Whatever's cheaper, though given the same price (as is likely the case), the 6750.

Thanks for the reply ill take a look at them.you wouldn't happen to know of a Nvidia equivalent do you?

The GTS 450 ($90 after rebate in this case) is equivalent to 5750/6750 (win some, lose some, or equal in gaming benchmarks).

looks like a great deal. I may buy it tonight. I will let you know how it all works out. Thanks to both of you for the replies. Love this forum as usual quick helpful responses!
