New Video Card

[Blubber]

You are talking about CPU usage but it's not entirely clear (to me) what you mean. I'm guessing you are looking the that windows task manager thingy? You will see 4 graphs (one for each core), is one core at 100% or all? Or is it the bar graph on the left side that is at 100%?

Because if one of your cores is getting 100% load but the others aren't then I would suggest you look at ISBoxer's CPU settings.

Ok cheers Mirai ill have to look at a new PSU then, it set to DX11 by defualt once the patch came out.

Any chance you could point me in the right direction for a PSU that will run those cards ?

Would this be any good ?

Although expensive.....Probably the last PSU you will ever need. (1.2kw @ 100a)

I'm getting a new gpu to upgrade my computer for 5 to 8 boxing.
I ordered this one : SAPPHIRE Radeon HD 7950 OC 3GB for 300€

Seems nice, 3Go are usefull for multiboxing, the gpu seems good and can be overclocked easily to be just 5% less efficient than the 7970.

So it will be in pair with a GTX 670, for a lot less money.

The bad thing is that i not a big fan of amd, bad compatibility with linux, and some games including wow are optimized for nvidia.
But i checked some benchmark and it seems that the gap is less important without multi-sampling.

Anyway, even if the game is nvidia optimized, it seems to me better to bet on his cheap 3Go video ram for efficient multiboxing.

So do you think it's a good idea, or do you have better option for a 300€ card ?
If i want to use nvidia all the gpu using more than 3Go cost nearly 500€.
Exept this one, but i think it could be not enought powerfull : http://www.newegg.com/Product/Produc...82E16814127684
But i'm still curious about this one, because i remember, back in the wotlk days, when my last gpu was HS, i temporary replace it with a 50$ passive gpu for 5boxing and ... surprisly it was working well. Not perfect but playable. So i'm curious about the real need of a powerfull gpu for multiboxing wow.

Thank you all for your help,

I think i may have found what the CPU issue was, when i installed the last patch the game went straight to DX11 so before starting i set it back to DX9 at the start game menu. I never knew there was another option that needed to be changed back in the in-game menu System > Advanced . I set it back to DX9 there also and CPU usage dropped by 30'ish %.

Thanks all for the help and advice.
