2 days ago a found a pc on my neighbor trash can, I picked it up and check what was wrong with the pc. The problem was its power supply is dead and replace it with my power supply and pc turn on with no problems. The pc specs are

AMD 3800 x2 2.0ghz ( i over clocked it to 2.3)
m2a-vm mobo w/integrated graphics
Patriot 3gb 6400 Lat:4
300gb sata Wester Digital HD
DVD-rw
TV Tuner
XP PRO

Will it be worth it to add an 8800gt card for $190 grand total? will it bottleneck with cpu? Will it play todays games graphics all max out with no lagging at 1280x1024 (call of duty 4, Bioshock, Rainbow six Vegas, Battlefield 2142, Battlefield Frontlines, Oblivion, doom 3, Unreal tournament 3, half life 2? SO, is it worth it adding an 8800gt since i dont have enough money to build an intel system?

Lol, just get the 8800gt. I don't believe it'll bottleneck the card, at least not by a lot. In any case, you got it for free, so if it does bottleneck, just get the 8800gt out and put it in the new pc. No harm done.

Wow, nice work! That's a $400 PC you got there, for the price of a new PSU. The tuner and XP alone would be like $200 together.

Sure, add the 8800GT. Make sure the temps are reasonable. If not, add fans or change the case. (You can use GPU-Z or nTunes for example to see them - anything under 80 Celsius is acceptable.) Or get an 8800GTS G92 512MB - it costs more but it's faster and overclocks better and pushes the heat directly out of the case.

What kind of PSU do you have? You need ot make sure it's powerful enough for the video card.

that's a solid dual core setup, go for the video card for sure, that thing will last you 2 years most likely

Yea you will be fine getting the 8800GT.

Best,

I have a Corsair 450 power supply, just got it about 3 months? at least this pc is powerful than my other slow AMD 2500 xp athlon pc.
