i recently bought a Gateway SX2803 desktop, i was VERY happy with the all around performance except when i tried to play FO3 and FNV.I want to upgrade my graphics card but i have no idea which ones are compatible with my desktop without changing other hardware as well. i wanna run FO3 and NV on highest settings with 8+ enemies on screen at once and constant explosions and fraps with high res texture packs on with no slow downs, i don't wanna spend alot of money on one either,and from what i heard i don't *need* an all powerful one with my 1366x768 monitor. i had in mind a GTX 550/560 but i was also recommended a Radeon 6850 but im not sure which one is compatible with my tower and fit inside and make fo3 and nv run smoothly on highest settings with small armies of enemies on screen at once. my price range on cards is 100-150ish, maybe a little higher but i want it to work seamlessly with my tower.

According to the spec sheet, the power supply is only a 220w, which is not going to be enough for any of those cards. I recommend getting at least a 500w PSU. Before doing that, you'll need to measure the inside of the case (over the PCI-E x16 slot) to see if any of the cards will fit.

I have a GTX 560 Ti and it screams with Fallout 3. Fallout: New Vegas also performs very well with it.

The Gateway SX2803 series is listed as coming with 1 PCI-e x16 expansion slot, which almost all modern video cards use. So your PC should be compatible with a GTX 550/560 in that regard. However, the same spec sheet states that the power supply in the SX2803 is rated at only 220 watts whereas the GTX series video cards recommend at least a 400 watt power supply.

Your power supply severely limits your upgrade options here, to the extent that I doubt there exists a video card which performs like you described but whose power requirements don't far exceed your system's capacity.

At least 400 watts. That's bare minimum. 550 watts or higher would be better.

Gateway SX2803 Rear View

The computer only supports low-profile expansion cards and uses a nonstandard power supply.

What graphics card is currently installed in the computer?

its the factory standard for my model Intel® G45/G43 Express Chipset
according to cyri labs my computer is too slow in the graphics dept to run nv and fo3 even tho i can run them on the lowest settings with issues. in fo3 it lags badly right after im out of the vault and nv is better but lag and bad frame rates arent uncommon when walking around and frequent in heated firefights.

There are some graphics cards that might be an upgrade, but I haven't paid attention to any reviews lately. Somebody else should know what the fastest low-profile graphics card is. The power supply output ratings are also needed, but someone else could explain that better than me.

ok so i need a better psu. i heard Corsair is the way to go, so can any psu fit in a desktop or is it like a graphics card where i have to be careful with part sizes? and is Corsair a good psu for Gtx 550? and will those parts fit in this tower or will i have to remove/replace the case?

Your one uses a smaller power supply size which is probably a mini-itx. Corsair is indeed a good quality power supply but they don't make any of those small sized ones unfortunately. Some graphics card has a low profile bracket but most new ones don't have it any more.

Yes and it's hard to find a good high wattage mini-itx power supply so your chances are slim.
