Which 4850 TM???

Which ATI 4XXX card would be the best for me??
Mainly for online FPS gaming,
i ll prolly buy another ATI card later on to Xfire em (maybe in a year and a half, addin another 2x2gb ram at the same time too)
here s my rig
E8400, 2x2gb 1000mhz, p5e mobo, 700w psu, 226bw monitor, a few more fan for better cooling, 7200.11 barracuda
i ll overclock this thing eventually (fsb up to 500 prolly) but i need to read more about that first (already blew one p5e up)
this rig didnt cost me much, like 1500$ with monitor (226bw) and all the gears... and i think its very decent for the price
im not much of a fan on spending many extra bucks for a few more power... i try to get the best bang for the bucks, without being too cheap too
you get my point, so which card would be best for me? also, when i ll eventually xfire another card, should i get another same card (Which will be ultra cheap in 1year and a half) or shud i get some other better card?
Tx a lot for your opinions/expertise

Tx in advance

Heya,

Best bang for the buck is the HD4850.

Note: The HD4850 and the HD4870 are the same card, the 4870 has a higher clock speed. So if you overclock the 4850, you have a 4870 for less money. And clearly, it will overclock. Just get a nice cooling setup (it's cheaper than the difference between the cost of the 4850 and 4870).

Very best,

I don't think the 4850 and 4870 are the same card. The difference is the video ram. 4850 is DDR3 and 4870 is DDR5. Regardless, I would choose the 4850 as well.

i bought an after market CPU cooler, and i added 1 120mm rear fan, +1mini fan
i think that might be enough as long as i dont xfire ? when the time comes, i ll then add some other fans or do a better setup
tx a lot
