It's just hit me.... Ok, I have a Radeon 9800 Pro 128 as you all probably know by now. They require AT LEAST 300Watts of power. Mine is running on a 230Watt, but as I say I get bad framerates almost anywhere. Could this be the cause of it? Do I actually need a better PSU for this card? PS: I have ordered a 520Watt :)

Could be. I would guess your card is not getting all the power it needs. I have a 9800xt on a 300Watt and it runs fine. 230W seems way too low for that card. 520W is nice ;)

even if your PSU isn't the reason for your bad framerate...upgrading to 520 watts is a smart move! everything nowadays that you buy for your system sucks a little more juice!

if you want some links to different tweaks for windows and in-game, lemme know, i'll send them to ya.

in general you should always have at least 350watt PSU.

also what cpu do you have?

here comes this speech again....

(note that i posted it replying to some othe rguy, so if i refer to something like "your bla bla bla" i was reffering to HIS system...)

I am the master at explaining how this stuff works. At least i think so. Peple normally write to me asking. So here: (I am so sick of posting this on so many threads)

Videocards opperate by Pipelines, much like your CPU. Videocard pipelines are very very deep and wide. The 9600xt features 4 of these pipelines, the 9800 features 8, the x800 12 and the 6800 16. Holy crap. That is a lot. Now you ask "so what?". Well when your videocard draws out something, it has to pass through the pipelines (the rule of thumb is more pipelines usually is faster) so if you have say 16 pipelines, it will do the work faster than if you have 4 pipelines. Now, these pipelines are beeing feeded by the CPU (your 1.2ghz athlon). If you have an 8 pipeline videocard with a crappy cpu, the cpu won't be able to issue enough instructions to the videocard. Pipelines are REQUIRED to be full at all costs, if they are not, all work that is currently in the pipeline will be tossed out and it has to start all over again, this results in lost clock cycles, you prbably loose some 40fps for 2 seconds. This could happen with the fastest CPU on the planet, and a 4 pipeline videocard, if the cpu messes up or something, it is very rare and it would only last 2 seconds. BUT.. if you have a 8 pipeline vodeocard with your cpu it will happen very very often.

Here is a little thing i made up myself to guide you.

4 pipeline: 1.8ghz P4 or AMD equivelent 8 pipeline: 2.4ghz P4 (w/HT) or AMD equivalent 12 pipeline: 3.0ghz P4 (w/HT) or an athlon 64 (any speed) 16 pipeline: 3.0ghz P4 (w/ HT Preferably extreme edition) or Athlon 64FX 51

Ram also matters, when i bought my 9600XT i had 256mb ram, it SUCKED. I upgraded and bought a stick of 512 mb, that helped alot.

generally you should always have at least 512 mb.

I hoped this helped.
