========

Ok, with all the latest games coming out, I need to be able to keep up. SO i need your help, helping me upgrade.

Im lookg for:

- RAM 1GB
- GFX card; 6800GT+
- PSU (i have one choosen)

So if you can help me find parts that will work well w/ what i have much <3

I am happy with my Mushkin purchase, and given it's value price, has performed very well, in my opinion.

As for GFX card, the X800 GTO2 is a very good card, which has a high success rate of being modded to have 16 functional pipelines.

PSU, you could get by with a Fortron AX500-A.

Some questions you should answer to help us are:

1. Will you be overclocking? If so, how heavily do you intend to do so?
2. What is your budget?
3. Whereabouts are you located?
4. Do you have a standard ATX case? I'm curious because of the 160w PSU you mention.
5. Exactly what model of motherboard do you have?

If I'm reading it right you want to do a few upgrades with your Dell. One of the upgrades being a psu. I could be wrong, but I know older model Dells were a pain to upgrade the psu, the wiring on the Dell psu's are different, than any other psu you would buy at a store, but I'm not sure about your model.

I had the Dell 4550 at one time and I know it had one of those psu's that was hard to replace.

my very old dimention something outta 1998 had the normal psu

According to this site the model you have 4700 does not need a special psu adapter.

From the looks of it, that dell appears to have half-height pci slots, and use a special power supply. I don't think you will be able to fit a standard power supply or video card into it. But... you can always take everything out of the case and run it on your desk.
