Build Help

So I use my PC for 60% watching streaming TV/Movies, 35% gaming (mostly DDO) and 5% surfing/other. I put together a build on cyberpower.com and cross checked everything price wise on newegg.com and i must say cyberpower is cheaper once shipping is added in. I just want to know if there's anything I am missing as this is the first build I am putting together. Also, I am not looking for top of the line, just better than average.

Some of my main concerns, Power supply, is 500W enough?

Do I need extra usb ports?

Is that Vid card good for streaming video?

Do I need an external wireless card or just the internal?

Quad core vs six core? Is there really enough of a difference to justify the extra $50 If I am using my comp for what I mentioned above?

I am sure I have more questions, just can't think of them currently. There is a link above that brings up the configurator if anyone has any ideas that are a must. Thanks in advance for your help.

 

Try this:
eXtreme Power Supply Calculator Lite v2.5

 

Yes

No

Yes

No

Absolutly none, VERY few games actually use more than three cores, so 6 cores over 4 is no advantage, especially at the extra money you would have to pay.

That build looks good, go for it.

 

Always a good 50-100w on top of this to account for effiency and worst case scanarios.

 

Thanks for the expedient replies geeks. It is appreciated.
