Try overclocking your video card here is a guide. They got 26% more performance. Also make sure you have the latest drivers. http://vr-zone.com/articles/Point_Of_View_Geforce_8400GS_Overclocking/5133-2.html

I would get the i3 2120 and spend the extra $ on a 6870 or 6850 if thats to much money but you will be glad you did the same PSU will run it.

Cut everything down to low with no eye candy other than that same answer as above. My wife has a AMD II 270 @ 3.4 GHz with a 6770 GPU runs it fine mid settings without the eye candy. Make sure your PSU can handle any changes.

Get a GPU check you PSU first for the power rating nothing less than a 6770 higher is better.

http://www.hwcompare.com/9701/geforce-gt-430-vs-geforce-gtx-550-ti/ or about $10 more http://www.hwcompare.com/9711/geforce-gtx-550-ti-vs-radeon-hd-6850/ Make sure your PSU has the power you did not list it.

When in instances server lag is a issue with the game servers not being able to keep up with the demand of players/amount of players running on the hardware it's their problem from a hardware issue or lack of hardware.

To cut to the facts this will run it very well $472 after the $40 rebates if you can count on that. Use your monitor or hd tv and a copy of windows 7 not going to say how to do that but. Everything works and at a budget with good performance. http://www.newegg.com/Product/Product.aspx?Item=N82E16811147153 http://www.newegg.com/Product/Product.aspx?Item=N82E16813138329 it works http://www.newegg.com/Product/Product.aspx?Item=N82E16814131374 i use these http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027 http://www.newegg.com/Product/Product.aspx?Item=N82E16819103886 use the stock cooler no overclocking. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231422 http://www.newegg.com/Product/Product.aspx?Item=N82E16822145299 http://www.newegg.com/Product/Product.aspx?Item=N82E16827106289

Wrong the 1gb 460 is much better. http://www.hwcompare.com/9691/geforce-gtx-460-1gb-vs-geforce-gtx-550-ti/ I would get the 6850 but i'm a AMD fan. http://www.hwcompare.com/8241/geforce-gtx-460-1gb-vs-radeon-hd-6850/ and the PSU is way overkill for that system. About the same price much better performance. http://www.newegg.com/Product/Product.aspx?Item=N82E16814161393 http://www.newegg.com/Product/Product.aspx?Item=N82E16817371031 http://www.newegg.com/Product/Product.aspx?Item=N82E16819103995 http://www.hwcompare.com/8240/geforce-gtx-460-1gb-vs-radeon-hd-6870/ The PSU I listed will handle anouther 6870 in Xfire later if you need it in the future with an adapter for the GPU power, use this to check Watts http://extreme.outervision.com/psucalculatorlite.jsp

Both systems with Windows 7 on 1080p monitors and 8 GB of memory built them myself. Mine i5 2500k OC to 4.4 with a 6970 OC to 940/1425 it melts the game like butter. $1100 Wife simple AMD Athion II x2 270 Regor stock 3.4 with a 6770 OC to 900/1225 Mid/High settings without the eye candy runs above 40FPS in the crowded places $400

That system will draw about 370 Watts.
