I just bought the HIS HD4890 from newegg (1GB), and it performs like a beast. Runs basically everything on über high. Sadly, I think that card is out of stock at Newegg right now. It's like 160 after MIR.
The card feels a little flimsy, but I think it's sturdy enough, and the performance is great.
I personally would go with a 5770. Performs like a 4870 which should be plenty for "some gaming". Supports dx11 so newer games will be supported, uses less power, gives off less heat and has more overclock headroom (40nm). Its selling around 170$ so its cheaper.
Not to throw myself to the other side, but the GTX 275 is a decent option as well... but given what has been looked at on this list, id say the Sapphire 4890 would be my choice. I almost got one before i found my 295, and I would have probably ventured into the 5000 series had i not found it... gotta love that GDDR5
