Hi, I recently upgraded to a computer with the following stats:
DELL OptiPlex 760 - Mini Tower Chassis (Full size Case)
Intel E7500 2.93 GHz Core 2 Duo 1066 MHz FSB LGA 775 Form Factor CPU
3.25 Gigs DDR2 Memory
One 250 GB SATA II 7200RPM Hard Drives
One 140 GB SATA Hard Drive
100 GB external HD
One 20X DVD+/-RW SATA dual layer optical drive
1.44MB Floppy Drive
Chipset: Intel Q43 Express chipset with ICH10D
Two (2) PCI Expansion Slots
One (1) PCIe x16 Graphics Expansion Slot
One (1) PCIe x1 Expansion Slot
Rear Mounted Ports:
Video (VGA), 9 pin serial,1 parallel, 6 USB 2.0 ports, ESATA, DisplayPort, 1 x RJ45, microphone input, speaker output
Front Mounted Ports:
Two (2) USB 2.0, Microphone input, Headphone output 305 Watt Power Supply
ATI Radeon X1300
I've been living with the X1300 for the time but I want something better.
I recently learned the hard way that my case will not fit a Geforce 9800 GTX.... opps.
I realize that I'll probably have to upgrade the power supply.
What's the best card my computer can support?
Yeah, that looks like a standard form factor PSU. What PSU and card you should get depends on your budget and what resolution you plan to play at. Knowing exactly how much space is available for the video card would help as well.
As for the graphics card, the PCIe slot is the highest on the board which means it has room above it if need.
The actual slot has enough room to go back a little over 10" but in the space above it you start hitting the fan after 6.5"
I'm only running a 17" monitor at 1280 x 1024.
The 9800 GTX cost $116 and it'll resell for more than that, so around that range.
That's not a good situation. It looks like you either need a single slot card or one that is smaller than 6.5 inches which rules out almost every powerful card. I believe there is a single slot GTX 260 but it's pretty expensive and it may actually be longer than 10 inches. Are you sure you can work a 7' dual slot card in there? Then you could use an HD5750.
It's actually possible the HD5750 will work with your current PSU so if you go for that one you might want to try it out before ordering a new PSU. If I remember right people have been able to use an HD4770 on that PSU and the HD5750 actually uses slightly less power.
Alright, just get the 9800GT then. It should be quite good for that resolution. Make sure it is one of the newer ones that doesn't need a power connector and then your current PSU will be fine.
That HD4850 would be a better choice for the money but you would need a new PSU for it and the performance difference at that resolution wouldn't be worth the hassle/money of upgrading the PSU. If you are considering a new monitor at any point in the not too distant future then a new PSU + the HD5770 is your best choice.
The older ones have a stock clock speed of 600mhz and the newer ones are 550mhz. You should be able to raise the speed back up to the normal levels and likely higher easily with overclocking software like rivatuner; http://www.guru3d.com/index.php?page=rivatuner
