Too much cpu usage HELP!

Before fix:
CPU: Athlon 64 3700+ (2.2 ghz)
GPU: Radeon R7 750 2gb
RAM: 2 gb
OS: Windows XP

After fix
CPU: Same
GPU: Same
RAM: 2gb (haven't installed 1 gb(still no need)
OS: Windows 7

I just recently fixed my computer while upgrading it to windows 7(I had XP before).
I was playing world of tanks and then I checked on the cpu usage and it said 100%!!!

That can't be right 'cause on my laptop when I play it says 36% and it's only .2 ghz faster(and it also runs windows 7)!

I checked the heat outside of the heat-sink with my finger and it seems alright.
It also seems some-what faster with XP(without consideration that it's less demanding).
On other games it does say 100% but doesn't affect the gameplay.

Can someone tell me what's going on!?

This CPU is VERY old and it is very possible for it to run at 100% CPU usage in a CPU heavy game like World of Tanks. Sounds normal to me.

Yes but it also says 100% usage when playing Prince of Persia: The sands of time,and that's 2003!

Yeah and that CPU is from 2005. Makes sense. The GPU you have is WAY too strong for that CPU and is causing the CPU to run at 100% to keep up. The CPU is simply old and antiquated.

I see no problem here besides out and outdated hardware.

I understand,but it never happened before the fix,and that's what's puzzling me.
Before the fix world of tanks ran fine with the cpu around 35%.

The upgrade to 7 may have greatly improved the GPU performance, thus creating a CPU bottleneck.

Also, unless your laptop has THE SAME CPU, it cannot even be considered in a comparison.

That probably answers it.
