I know there are a ton of experienced PC builders here so I feel like I'm in the right place. I seem to be having a little bit of trouble installing my GeForce 9800 GTX+ correctly. I've never installed a card that was this nice, or a card that needed extra power connected to it from the PSU. It's a big card, and the obvious issue was trying to fit it on my micro ATX motherboard. (I know, irresponsible buying)

The current issue I'm having is performance. I saw a bunch of benchmark tests, and nothing I've tested even compares to the official tests. I put it in my PCIE 2.0 x16 slot, and only connected 1, 6 pin power cable, connected the monitor, turned on the PC, uninstalled the ATI drivers from the onboard video (not the chipset drivers) and restarted the PC. Then I installed the Nvidia drivers, restarted the PC, and it gave me an error from Nvidia saying there was not enough power to the video card, so i connected the other 3, 6-pin power cables to the video card. There error disappeared.

Now that the power error is gone, i was trying some games. On recommended settings in the video settings in Team Fortress 2, it was fluctuating between 60 FPS and 20 FPS. More so consistent around 30 FPS. Now obviously that can't be right, and i know a bit about framerate in games and what to expect, but with my on-board video, i was getting a constant 25.

Is this a power issue? Did I install it incorrectly?

I have a 500 watt power supply.
AMD Phenom 9600 Agena 2.3GHz Quad core 95w
4 gigs ram at ddr2 1066 (windows XP only registers 3 gigs of it)
Gigabyte motherboard (link below if you need to see it)

Any responses would be greatly appreciated. I would love to know more about how to install correctly, and get the best performance from my video card. Thanks guys.

notice the test system specs. most reviewers use top of the line intel extreme qx9650 to benchmark cards. its your amd processor that is holding the graphic card. i have q6600 with ati 4850 (same in terms of performance like your card) and when i tried running card with my cpu at stock settings (2.4ghz) and then gave it healthy overclock (3.4ghz) I seen 14-30 fps increase. so its your slow cpu holding this card back

i believe a 9800gtx+ has 2 six pin connectors try connecting both first. 500 watts should be ok. and that card should max out TF2

second it could be a driver problem make sure you have the the right drivers

hope this helps
