Hoping that the stock fan the Amd processor comes with will be okay and won't be loud.
Am I missing anything from this build?

g36hk5 your latest build mixes an am2+ mb with ddr3 ram. These components are not compatible .

Skora and batuchkas builds are a generation newer and much more powerfiul

Hang in there, the only way I learned was asking questions and doing things that made many a vetrans roll their eyes. We all sat at the starting line of knowledge too.

If its a quad core you want, get this case:
$40 free shipping

And this CPU/Mobo combo:
$246

Total $803 amir

If you didn't want to spend all $800, tell us what you would prefer to spend. We'll try to give good suggestions and what can be cut. For example, you could get the 1680x1050 monitor, the cheap keyboard, and a 512mb 4870 and save $33. With a $40 case, thats only $727 and performance would be similar, just a smaller monitor.

Do you know how to look up combos on newegg? There's a lot of money that can be saved that way.

As for your "real" final build, its a bit unbalanced. The GPU isn't strong enough to properly power that monitor unless you are lowering settings. When I spec out a build, I start with the monitor. Lets look at the 1920x1080 that is picked. That's 2.1 million pixels to calculate. A 1680x1050 is only 1.76 million. The 4850 512 has a hard time with 1.76 million and is really lost at 2.1. The 4870 has a little trouble at max settings at 2.1. For the price, the 4870 1gb is a great match for 1920x1080. The 4850 1gb is a good match for 1680x1050, but I'd prefer the 4870 512 for that resolution. Most any monitor will look great for gaming. This article will explain that most all the monitors will do the job very well. http://www.anandtech.com/displays/ [...] i=3584&p=2

As for that PSU, not a good pick. Since you only have 1 pcie 2.0 x16 slot, the most any GPU will need for the type of gaming you do is 550-600w for the top end cards in the resonable price bracket. Kinwin is far from quality. The efficency alone is a clue of quality. Take a look at Proximon's Big List of Recommended Parts. Won't find it on there. For the price, the Corsair 550w is a great unit and if you do go with a 4850, the OCZ 500w is good too.

If you can balance out the monitor/GPU/PSU, you're going to have a good build. Take our recommendations with a little more weight, they are good choices.

The 4850 just isnt powerful enough to get good frame rates and high quality settings on a monitor with a resolution that high . It would be ok with a 1680 x 1050 resolution and thats an option for you to switch to a 22 inch monitor with that resolution .
An alternative is to upgrade the gfx card to a 4870 , and keep the monitor you have listed . There are definite advantages to a 1080p monitor .
This
POWERCOLOR AX4870 512MD5 is only $117 after rebate
http://www.newegg.com/Product/Prod [...] 6814131140
and then you can keep the monitor , and game ok

You can even do it without spending extra if you swap out the ASUS motherboard for this identically performing and equal quality Gigabyte GA-MA770T-UD3P AM3 AMD 770 ATX
http://www.newegg.com/Product/Prod [...] 6813128392
which is only $70 ATM

And the PSU in your list is one rung above being a doorstop , but only because it will be a good conversation peice when your friends ask you why you use it for that

Wow thanks alot. I found which setup was good for me and my budget. Btw do I need to get a sound card?

A quick question. Does acer make good monitors?

That looks impressive for the price. Gigabyte also offer a full size ATX motherboard based on the same chipset that I'm looking at myself. It should perform pretty good.

@philymcrae - start your own thread and we'll be glad to help you. Hijacking someone's thread isn't the way to ask for help. Your request for help in your new thread should also follow the format in the "How to ask for new build advice" sticky at the top of the forum.
