Ok guys, this is my first time build and I have a budget of around $800. I already have a case and I am wanting to play AoC with no lag at all and future games such as starcraft 2, diablo 3, and any other game I might feel the need to play.
Here is my system please let me know what you think.
BTW- I am just guessing with this PSU. Is it the right one? I don't know how to get down to the specifics of what I actually need.
700 or 750W powersupplies are WAYYY overkill for your build. You should get a quality 500ish W PSU. geofelt's suggestions are good - I think the 450VX will be more than enough, unless you're planning to add a second card down the line. I think that the x8 link would then bottleneck the cards, but it would still provide a benefit in some games. And the 610 Silencer could handle two 4850s easily.
For a total of $753 after rebate(s) and some stuff has free shipping.
It's common knowledge buy.com has the best prices on Corsair PSU's, which are generally the best bang-for-the-buck in their price ranges.
ewiz also beats out newegg on CPU prices, the AC 7 cooler, some motherboards and their shipping is more reasonably priced.
The two hard drives I pointed out have free shipping, which makes one the same price as the hard drive you pointed out. And believe me, two hard drives make everything load fast and gameplay smoother. Well worth the extra $50.
I think Noya has the better solution for your budget and needs.... or keep the P5Q and go with the rest. You need to look at where your biggest performance gains will come from, and that is certainly the video card.
Noya did a really nice mock build. He also put a lot of time in to researching the best prices too.
I agree with the suggestion of the e7200. It is still a FAST chip and will save you money on your budget.
I also agree with what the others are saying. You really need more than 160GB for hard drive space. I would not consider anything less than 250 GBs. An extra 100 GBs really does not cost that much more.
You may also want to go with the 4850 also. It will trim $100 off your build and offer 9800GTX like performance which is very good and should handle Conan and Star Craft 2, and Diablo 3 nicely. Of course it is not as fast as a 4870 but I think it has a better 'BANG FOR YOUR BUCK' ratio.
