Hello, I'm looking for help concerning upgrading my graphics card. The kicker is that I have a Shuttle SFF system.

The power supply is the SilentX 350W. Here is a picture of the power specs on it. http://forums.hexus.net/hexus-hard [...] u-56k.html

I am wondering what kind of newer generation graphics card I could both fit in my system and power effectively with the power supply that I have.

For frame of reference, this is my old card: http://www.newegg.com/Product/Prod [...] 6814125156

Any help offered would be most appreciated.

Hmm... it's going to be hard with out a PSU upgrade.

An 8600GTS is five tiers up on Cleeve's performance table, and would make a big difference. Still, if you want to play the newest games on high settings, you'll need to go even higher, which will require a PSU upgrade. I can't view its picture here at work, but if it isn't a standard ATX-sized PSU, you might need a new case as well.

Your 6600GT uses 48w of power.

The safest and still a good upgrade is a 8600GTS at 47w $54

A stretch for your PSU in watts and amps would be a 8800GS at 59w $80 after rebate

not recommending the 8800GS though.

from EVGA system req for the 8800GS
"Minimum System Requirements

1GB of system memory

CD-ROM drive

50MB of available hard disk drive space for basic driver installation

Microsoft Windows XP, Vista operating system

PCI Express-compliant motherboard with one vacant PCI Express x16 slot

Minimum of a 400 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 22 Amp Amps.)

Minimum 450 Watt for SLI mode system.
(Minimum recommended power supply with +12 Volt current rating of 24 Amp Amps.)

An available 6 pin PCI-E power connector (hard drive power dongle to PCI-E 6 pin adapter included with card) "

What about the new 9600 low profile? I didn't check the power stats but it should fit in his case right?
