That's an awkward situation that you are in right now, wanting to upgrade both at the same time, especially so close to Haswell's release and Nvidia's 700m series GPU's just having come out.
For the desktop, you can upgrade at any time, Haswell or not, and any quad core i5 will suit you just fine, and you can pair whatever GPU you want with that. Haswell will bring some features and some better performance but if you really don't want to wait then you don't have to.
The most awkward situation is with the laptop. You want something right now so that you can be gaming on the go ASAP, but Nvidia's 700 series cards haven't been fully flushed out, and the ones that have been released are still sparse. Thankfully though there is currently a 700 series that would fit your needs, the 750M so if you wanted the latest hardware out right now (though it's really just a minor update over the last series) then that would be a good GPU, but even the 740M would be good. Once models start getting replaced with the 700M series, then their 600M series counterparts will go on sale. Hardware refreshes are a great time to buy an ASUS at the same price that Clevo barebones go for. While you normally save crap tons of money by going with a Clevo barebone or MSI laptop, neither of them are as good as ASUS laptops typically (especially when you factor in warranty). ASUS doesn't seem to have updated their laptops with the 700M series yet but I am sure that they will if a few weeks, then you will see some model numbers go on sale so if you want to wait a couple of weeks and see what happens there, so that you can get a better laptop, then go ahead on do that.
Of course, the biggest money savings is if you waited for Haswell, then Ivy Bridge models will get very large discounts and you could pick up a good Ivy Bridge system then, but that's nearly 2 months out still. And you can't do this game where you wait for new tech to come out with Clevo barebone based computers because they don't have a huge stock they need to get rid of when the change happens, so you don't have a bunch of retailers and people on Amazon giving you a big discount so if you are thinking of using this new-tech strategy for the less expensive gaming laptops, it just won't work out that well.
Too bad you don't have this situation happening in a couple of months with Haswell! The CPU, power, and integrated GPU optimization are definitely going to be felt in laptops. But, for your current situation I suggest two things, first: http://www.xoticpc.com/asus-n56dpdh11-p-4979.html
This laptop will play games at medium settings, it looks nice, has a really good warranty (1 year accidental is included), comes with an operating system, and it's fairly cheap. You can then spend the rest of your money getting a good desktop.
Second suggestion goes along Imglindinhere's suggestion, and just get a really nice laptop. You will find that when you have a nice laptop, your desktop gets rather neglected and goes unused. Why use your desktop when you can take your laptop to the couch? The bed? Heck, even the toilet! It happened to me and my desktop and it could happen to you. Yes, I can't game as well on the laptop as I can on the desktop, but I can still game pretty damned well. In this case, I'd go all out and get something very nice like this: http://www.xoticpc.com/msi-gt60-0ne403us-p-5317.html?wconfigure=yes
Only thing I'd change on it is the 12GB of RAM to 16GB (3 DIMMS is dumb, it's a dual-channel chipset so either fill 2 or 4, not 3 or 1 xP) And it comes with a 2 year standard, 1 year accidental warranty.
But to be honest, I wouldn't go the route of doing both laptop and dekstop until Haswell comes out. Haswell will bring more powerful, more portable, and more affordable laptops with it so if you're going to run a tight budget, you'll get WAY more bang for your buck with Haswell.
