hi, first post ^^ ... i'm thinking about upgrading from my mx440 to a BFG 7800gs oc agp
the concern is that i'm not sure if my system is compatible/ "run the full potential of the card." i know i would be seeing major differences from the card, but i have heard that due to my cpu the quality won't be any differences from the radeon 9800 series, is this true?
i don't want to be upgrading to PCIe as i would be needing to buy whole new system; with my current system and the new gpu, would i run the new games in high quality (i.e oblivion)?
(i'm very newbed so i'll provide quite in-depth) my system specs are as follows:
- GA-8I848P-G mobo

-1gb ddr-sdram

-p4 2.8ghz specs:

- 128mb mx440 (upgrading to 7800gs oc agp)

-my psu specs:
brand: solarmax
model: kc-400 ATX
input: 115/230v AC: 50/60hz
7A/3.5A
output: 400W MAX
+5v 28A +3.3V 19A
+12V 15A -12V 1A
+5VSB 1.5A -5V 1A
the psu is probably insufficient so i'm considering the stock psu that comes with the soprano case http://i-tech.com.au/products/2569_THERMALTAKE_Soprano_...

-thx-

You should be fine with a 7800GS. You have better stats on paper in every area then mine except for RAM. My rig is in my sig.

I recently purchased the similar Gainward 7800GT AGP version and put it in my system which has almost exactly the same base specifications as you listed in the original post (although I have done some modest overclocking). I've been getting very good performance. I did have to replace my PSU though as the card uses a lot of energy, plus I have slight heat issues.

However, you should be just fine as long as you get a good PSU.

for the minimum specifications of the 7800gs oc agp, it says that it needs a minimum 400w system power supply with 12V current rating of 20A or more, i understand the 400w requirement part, but not sure about the 12V current rating of 20A part. does anybody have any recommendations? .. and is avalable in australia

It really varies from one PS to another. And by the way they've changed the minimum spec, to 350w. If you have a quality 350w with a nice 12v rail it shouldn't be a problem. I just boght a 7800gs (waiting on delivery), I have the Antec Sonata case with 350w stock PSU and I found someone posting to some forum or other with the same PSU that had no problems with this card.
