As some of you already know, im in the process of building a low/mid rang gaming rig for my kids.I posted a post a while back about what GPU would be the best at $120(give or take $10) and most of yall said the 5770 out of the ones i chose(5770,550ti,4870).now that im ready to put the order through i see that they(newegg) has a 5850 for $144. i know it is $24 over budget but the performance i get from the 5850 is waaay worth the extra $24, IMHO.Now my question is; will the Athlon X4 640 bottle neck the 5850?because if the athlon bottle necks it bad than i will just get the 5770,or 5830?

The word bottleneck is used too often and for the wrong reasons. The CPU will be a bottleneck for CPU-heavy workloads, not the GPU. The reason people think it does is because of synthetic benchmarks, namely 3dmark06 and vantage, where a faster CPU speed led to a higher GPU score which is entirely false. I believe 3dmark11 corrects this.

EDIT: To clarify, no it won't.

thx bro.nicely explained.So... you think that 5850 is a good choice?oh sh!t,almost forgot...will the 5850 run on the PSU i already have?

It really all depends on what you mean by bottle neck. If your talking gaming. Then yes a CPU can bottleneck a GPU. Depending on the game, some are more CPU dependent then others. I mean if it didnt everybody would get the cheapest, lowest clocked X4 they could and get a 6990 or 590.

Everything else equal, you have one system with a 2500k and one with a Athlon II X4 630, both with a 5850. The 2500k system will beat it in FPS everytime. How much in each game is like I said above, it depends on how CPU dependent the game is.

For the price your getting it at. I dont see any reason to get a 5770 or 5830 over it. Go for the 5850.

That will be fine but you won't have any room for upgrades.
