View Full Version : upgrading graphics card

Hi all

I want to upgrade my video card!

Dell Dimension 8200
Windows XP HOME
P42.2 GHZ

I downloaded SiSandra software and got this info about my AGP Slot:-
AGP Bus(es) on Hub 1
Version : 2.00
Speed : 4x
Multiplier : 1/2x
Fast-Writes Enabled : Yes
Side Band Enabled : Yes
Aperture Size : 128MB

The speed says 4x does that mean that i can run an 8x video card?..or if the card supports both 4x and 8x will i suffer in performance?

Aperature size says 128mb, does that mean i can't run a 256mb card or higher?...or if i do will i suffer in performance?

The card i would like to upgrade to is, BFG Technologies BFG686256GTOC Geforce 6800GT 256MB or BFG Technologies GeForce 6800 Ultra 256MB DDR3. As far as i read on the specs it does not require a PCI Express slot

Someone told me that the 8200 carries a 250watt psu so i cant upgrade to either of these cards. I read something similar on the forums here also.

Does the dell psu in my 8200 only affect the motherboard really?...so i can get another psu and connect to the other components like the video card etc?...and is this safe?

Thanks for any help!

You will need a bigger PSU or a secondary PSU in order to power those cards. You can buy a new PSU from Dell, but it will be expensive. The other option will require more research on your part, unless someone else here has a link.

You can run an AGP 8x video card, and you can run a 256MB of 512MB. A 128MB aperture is fine, and it won't affect what cards you can use.

Regardless of that, your processor can't take advantage of a 6800GT or Ultra anyway. You'd be better off with a 9800 Pro, 6600GT, or regular 6800. The former two are probably okay on that PSU, while I'd want a bigger for the latter.

Ok, found this power supply


Will it work with the graphics cards you suggested?

Also i read that my psu may not be propriety but i am not sure....hmmmm


it's toward the end of the article,

and this from the dell message boards

That power supply looks like it would work. Personally right now, with the computer you got, I would go with a 6600 gt and save money to build a new comp. Your processor is extremely limiting you right now. Any top of the line graphics card with that processor will be extremely limited.

The power supply should be enough for a 6800. You can research and determine whether or not your specific model requres the use of a Dell PSU. If you're pretty sure it doesn't, you can go ahead and get a non-Dell PSU. To keep things cheap, I'd say something around 420W to 450W from Thermaltake.

As for replacing the system entirely, it's agruable. Your processor will limit you with anything but mid-range cards, but it's fine for modern games and it might be another year before your average game needs enough CPU performance that you're in bad shape. Personally, I'd be saving up for a new system just because the added cost of using that Dell PSU makes upgrading now more economically painful than it ought to be.

You can get a 6800 and unlock some of the pipelines and vertex shaders and overclock it without generating artifacts and heat, plus it will outperform the 6600GT (and yes, I have both of them and have tested them in the same machine). Otherwise pick up a 9800Pro and don't bother upgrading anything until you have a new system.

9800 pros are getting very cheap and it would completely rock your world compared to what you are using now. Anything more will be a power hog on that system.
