Heat generated by videocard?

[SwooshingRob]

WC experts,
Due to fan failure I had to make some changes in my watercooling project schedule. :(
Last night I mounted a waterblock on my GPU, but since I haven't got all the parts in place yet the setup is as follows: reservoir -> pump -> GPU -> reservoir.
Furthermore the amount of water in my system is 2 litres. Measuring the temperature changes of the water I found that the GPU and pump generates about 15 W (it took about 10 minutes for the water to get 1 C warmer at around room temp) and my reservoir dissipates those 15W at 35C (stable temperature).
I have a low end graphics card, FX5200, so what I'm wondering how much more heat I would have to deal with once I upgrade? Is it reasonable to expect 30W or even 50W?

Cheers,
Rob

5200 puts a very little amount of heat compared to a 9700pro so to say. i had my cpu temp rise 2c after installing it. for a radeon 9700pro, i would guess that it puts out ~20-25watts or less (depending on overclocking and the game u play). i would guess that something like the 5950fx would be the only card to put out close to 50watt, but thats only to reference of the larger stock heatsink it comes with.

bump...this estimate sounds reasonable, i dont think youll have a problem.

Thanks guys.
I just wanted to make sure I build some future-proofing into my system. I'm not really a hardcore gamer, but I want my cooler to be able to cope with a decent graphics card. I will put 30-40W into my calculations.
(FYI, I tried this 3dMark you kids are running all the time. My system reached a whopping 937, with some of the tests running at 3 fps. Now that should be a result that blows you away...)
