I have both motherboards, and i want to know which ONE should be the one to use for gaming and watching hd movies on (POWERFUL) and which one to listen to music and use photoshop with (less powerful)
What tells me the strengh of a pc? Is it the processor's highest number? Please inform me.
Here are the specs:
P5E-VM DO: http://www.cnet.com/products/asus-p5e-vm-do-motherboard-micro-atx-lga775-socket-q35-series/specs/
P5E-VM HDMI : http://www.cnet.com/products/asus-p5e-vm-hdmi-motherboard-micro-atx-lga775-socket-g35-series/specs/

The winner will have 8gb of ram put into and the other 4gb until i find a deal on ram.The motherboard is virtually irrelevant in terms of performance therefore the one with the Q9400 would win as it is by far the better processor.Can i simply swap the Q9400 processor into the P5E-VM HDMI without flashing or anything? Because I prefer the fan control in this one.I can't see any reason that you couldn't, the boards are virtually the same.I succesfully did it, WORKS greatDid what ? ?...decided ? i switched processors, uptated bios on both, and they work great...ISH?
I dont really notice that much difference in both computers.
My next step would be to make them both silent as a cloud.
I dabbled into speedfan and bios Q-Fan options. I have so many questions left unanswered.
Is all that noise a question of processor?thermal paste?fan quality?motherboard's year or brand?
It's not THAT noisy but i always want to know more in the quest of a semi perfect computer for my liking, and i dont play 3d games or multiplayers online and such.
Im an old school gamer, i like myself a good 8bit shovel knight or at best ori and the blind forest. I watch 720p quality movies at best for my tv capacity.
It aint much. So what make the systems become hot with what i got?

Asus P5e-VM HDMI with Q9400 Processor and latest bios available
8gb of quality corsair 800mhz ram and a thermatake 430w powersupply.
What would be to do? You'd be best to actually listen to the PC and try to find out what is making the most sound, it could even be your hard drive vibrating. You may find that new, quieter fans or anti-vibration mounts for your hard drive may help.
