does the 8800gt beat the 8800gts on both price and performance?
I'm not sure about the price (yet), but the 8800GT can beat the 8800GTS and can give the 8800GTX a run for it's money in a few cases. Actually the 8800GT can even beat the 8800GTX in some cases. See the link below for some benchmarks:

As for a PSU, if you are willing to spend big $$$ on a GPU, then you should be spending a decent amount of $$$ on a PSU. A PSU failure can (under the worst possible situation) destroy every single component in your PC.
The following are PSUs that I would recommend based on my knowledge of their quality.
Thermaltake Purepower W0100RU ATX 12V 2.0 500W Power Supply - $35 after a $25 mail-in rebate.
Thermaltake PSUs are decent and I'm sure you will like the price. The most important thing about PSUs (other than build quality) is the amount of amps available on the 12v rail. This one has 14 amps, and 15 amps on the two 12v rails. It would be nice to simply add them together, multiply by 12v to get 348w. However, those amps are peak, not constant. I would guess the actual total amperage will be closer to 23 amps, or 276w total on the 12v rail.
FSP Group (Fortron Source) AX500-PN ATX2.2 500W Power Supply - $60
Fortron or FSP is a well respect PSU manufacturer who makes good quality, basic no frills PSUs. According to the sticker on the PSU each 12v rail can provide up to 18 amps each or 36 amps total. But lower on the sticker it's stated that the 12v rails can provide 360w of power that means actual total constant amps is 30 amps (360w / 12v). I would choose this PSU over the Thermaltake.
CORSAIR CMPSU-450VX ATX12V V2.2 450W Power Supply - $70 after a $10 rebate.
The VX series covers the value market for Corsair. This PSU can provide 33 amps on the 12v rail, or 396w. That's assuming the other rails do not consume more than 54w in total ('cause 396 + 54 = 450). I would recommend this PSU over the Fortron. It is also rated at up to 85% energy efficient which means less electricity is wasted as heat by this PSU. That means slightly lower electricity bills and the PC doesn't get as hot.
Seasonic S12 430 - $75
This is PSU that I would recommend. Okay, it's the most expensive PSU I'm recommending (unless you exclude rebates), and it is the least powerful, so why am I recommending this one?
This PSU can provide 30 amps on the 12v rails (34 amps peak) for a total of 360w; assuming no more than 70w is being consumed by the other rails. Seasonic builds high quality PSUs that are not only energy efficient (85%), but they are also very quiet. You will hear the other fans in your PC before you will hear the 120mm fan on this Seasoinc S12 430 PSU.
, but now ive opened my case to find out that there is a liteon model no: PS-5301, is that by any chance powerfull enough?, and an older PC i have has got an Apon, model no:ATX-300GTF, is any of them any good? otherwise i guess i have to pick on of the list u wrote
