I am looking to buy a new video card and have around 150 to 240 to spend. I am looking for something that can run doom 3 and some of the newer games, without any hangups. Any advice would be much appreciated.

A Radeon 9800 128mb is going for around 100 USD now, great card. If you want even cheaper but a card that will run every game, just not on highest settings go for the Radeon 9600. If you really want to spend the bucks then check out the nVidia Sli's or the 512mb Ati cards they got goin on. They are crazy. Another great card is the nVidia 6800 256mb or the GT Version, both are pretty pricy.

*Edit* sory didnt see your price range, forget about the SLi's
My crappy Radeon 9200 can run doom3 fine, they go for 30 usd on ebay if oyu feel cheap.

if you can come up with another $100, I would recommend the Ati X800XL.

For 245 USD here is a good card

NOTE:I picked these assuming you had an AGP 4/8x slot. and that the 6800 and 6600gt are both on sale for a good price
