Before you get reading, know this: two of these computers have i7 processors, so, even though they're in your price range, if you only want to get an i5, go all the way to the second to last paragraph.
Back in the summer, I was in just the same boat as you. My price range was $600-1000. I bought my computer with $935 and I'm very happy with it, maybe you would like it. It is:
Samsung RF511-S02
15.6" 1366x768
Although some reviews of the computer complain about this being low but, although I can't remember the last time I saw 1920x1000, I find the 1366x768 looks fine...
i7-2630QM @ 2.00 GHz + Turbo Boost (Max Freq. at 2.90 GHz)
Nvidia 540M with 1GB Dedicated Memory
4 GB Memory
Note: Samsung is not like Apple, they give you one stick of 4GB Memory, not like Apple with two 2GB sticks, so it is EASY to upgrade to 8GB
Note: I believe that the "S02" means you get 4GB RAM, "S03" means 6GB, and "S04" means 8GB.
500 GB Hard Drive @ 5400 RPM
Two USB 3.0 ports! A great way to stay with the times!
Note: It also has two USB 2.0 ports.
Webcam
~5.6 lbs1
EDIT: The sound is also godly. I still can't quite comprehend how my laptop sounds so good and is just so loud...
EDIT: Oh and another thing I would like to point out is that the RF511 can play Skyrim on ultra and still maintain around 20 FPS... The fact that anyone could buy a computer for $700 or less, as I talk about a little below, and play Skyrim on ultra is crazy! To maintain a steady FPS above 24, I keep a sort of hybrid in between ultra and high.
...
One Downside is that it has only around a 2 hour battery life: 45 minutes when playing Skyrim and 3.5 hours when Word processing with brightness all the way down
However, it's not sold anymore, which is (I think) due to the fact that Samsung is rolling out lots of new laptops like the Series 7 or whatever they're called. But some used and refurbished ones are sold on Amazon, and I'm sure they're sold on Ebay. The used one I saw on Amazon was $735 and the lowest priced refurbished one was 574.91.
When I was looking for laptops back in the summer, Samsung laptops really seemed to fit my needs. Here are some other Samsung laptops I was thinking about purchasing:
Samsung RC512-S0(1,2,3)
Note: I'm rather confused as to what the S01, S02, and S03 mean here. I don't think it's RAM... The Samsung site doesn't even say what the laptop's processor is (it's an i7)...
Here is a site that gives info about the laptop:
http/www.pcmag.com/article2/0,2817,2383822,00.asp?tab=Specs
This laptop has around a 5 hour battery life, as the internet says at least.
The RC512 is very MacBook Pro-like because it has an aluminium chassis.
Alright, finally to a laptop with an i5, like you asked for!
This laptop is like the little brother of the RC512: it has just about the same stats, except it has an i5 and a 14" screen. I'm not sure about any other differences.
The laptop is $600 on TigerDirect and $800 dollars on Amazon, per Cnet.

The worst Cnet could say about this laptop was this:
"This laptop has a finicky clickpad and a heavy, rather wide build."
Way to just try to find something bad Cnet, so that it doesn't seem like you like the computer too much, LOL!
Speaking of clickpads... the mouse I'm using at the moment I would also highly recommend. It is a Logitech Anywhere MX, which can work on glass, has five buttons which can be set to do things like open programs, click keys (useful in Battlefield 3), and other macros (two buttons are right by the thumb, and one behind the click wheel. The other two aren't really buttons: you can sort of "click" the mouse wheel to the right or left, which will do whatever you have set it to do.)...
I highly recommend that mouse.
Alright, I hope this helps a lot!
EDIT: Now, I'm not looking to compete, troll, or anything like that, but I'd just like to point out that my Samsung RF511 not only costs less (by $100-200 depending on where you get it from) but also outperforms xtreme5's XPS15 by far! The only thing the XPS 15 has up on the RF511 is memory which can be upgraded to 8GB (therefore surpassing the XPS by 2GB) for around $25...
