Need Opinion Before Buying Parts

It was recommended to me and it runs cool. Also has hyperthreading. Is there a better one for games/video editing? (for around the same price)

As far as I've seen it looks good for the price!

I would recommend against a sound card as your mother board has on-board sound.

Instead if you want to get a better sound set up down the road I would get an external DAC and Amp.

For $600 ( gaming) I would reccomend this pc:

Replace that power supply with something a bit cheaper if you need to bring the price down a bit...

Because that system won't use 650W and doesn't need a modular power supply.

Look for like a 400W power supply and if you have any left over for the budget upgrade the CPU a bit.
