will that processor with no overclocking be able to fully use the 5870 for should i just go with the 5850? thanks....oh running in 1920 x 1080

You'll be fine with either card.

But if you like to overclock, get the 5850 with a good aftermarket cooler (HSF) and get a greater bang for the buck IMO.

Nope you shouldnt have a problem with bottlenecks... The I5 by Intel is pretty good and since its a quad core you should be just fine with either of those cards

well either one will work just fine and btw overclocking isnt hard with ATI's cards... When u install cards you also install a thing called Catalyst Control Center in it there is a thing under option which will mainly overclock the video card thus raising performance, it will also make sure it doesnt overheat and it shouldnt cause any real damage besides maybe causing the card to have a shorter life although it really isnt a problem since graphic cards need to be updated so much...

The 5870 though is the fastest single gpu card out right though (Although the GTX 480 is coming out in retail this april 12th and will probably take that title)... so if you dont want to overclock go for the 5870 (which can overclock as well lol)

I don't like to use the work "bottleneck" as it is a poor and misused term. But I am here to tell you that even an i5 running at 2.6 ghz is not going to push a 5870 to it's full potential. People, when you are talking about gaming, more mhz, more mhz, and more mhz is still important. 5870? You want something running at 3ghz or more, I don't care if it is an i5 or even an i7.
Now, I am not saying don't buy the 5870. But if you are going to spend the money on a 5870, put a faster processor in front of it.

I'll attest to what JTPub has said. I thought my E8400 @ 3.0 Ghz was already getting all out of my "lowly" GTX 260 but to my surprise the GTX 260 kept giving more at 3.2 Ghz, 3.6 Ghz and 4.0 Ghz! And even at the same 4.0 Ghz, it pushed even higher framerates. What do I mean? At 4.0 Ghz (9 multiplier x 444 bus - 177 fsb) it scored the highest framerates on my system in 3dMark06 benchmarks. Then at 4.0 Ghz ( 8 x 500 bus for 2000 Mhs FSB) the framerates and render scores went even higher from the increased speed, bandwidth of the faster FSB.

My E8400 didn't post at 4.% Ghz but I didn't want to go past 1.375 on my vcore so 4 Ghz for now. My point is this - if my lowly GTX 260 was only giving out 75% of its full capacity @ 3 Ghz, 1333 FSB, probably a 5870 would only be pushed to pump out 60% of its full capacity. So yes, a stock i5 - 750 is a significant bottleneck for that card.

Good choice. But even that 5850 will scale nicely if you ever do decide on a faster processor, or even maybe if you decide to clock that i5 just a little faster... :)  But anyway, I think value wise, that is a much better choice, have fun.

I'm new to OC'ing but the i5 750 (and i7 920/930) both seem pretty easy to run up to pretty high speeds- plenty of guides available here on this site and plenty of others. You should give it a shot, will create a lot of value in your system especially if you are working on a budget.
