Points:
I think both builds have nailed the essence of a build at this price so my comments will be minor and BUDGET will also factor in.
1) Either graphics card is fine, but if possible get this card ( Asus GTX770 DCU2). It's just awesome.

2) SSD.
The Samsung 840 is a great SSD for the price. If you can manage get it as well, but if you can't afford it AND the GTX770 my advice is stick with an HDD for now and get an SSD later.
3) GAMES on SSD/HDD?
An SSD isn't a huge deal for most games. I did lots of testing. If you do get an SSD and an HDD, put Windows/apps on a 120GB SSD, and Steam/other games on the HDD.
4) BACKUP IMAGE:
It's a good idea to have two drives and periodically create a backup IMAGE of your Windows partition.
5) POWER SUPPLY:
I don't recommend any lower than a quality 650Watt PSU. You can save a few bucks with a 550W but there are goods reasons to get a 650W or even 750W but that's beyond the scope here.
SHOP AROUND and READ REVIEWS for the PSU.
6) DVD drive:
Check the support site for any DVD drive you're considering and don't buy one if the firmware is older than 2012 or it will be more prone to create bad burns. I saw an Asus DVD drive that was 2013 and another one that was only 2009!
7) CPU Cooler:
Make sure it has a PWM fan as that's required for most motherboards to get fan control to work. 12cm fan recommended. My example:

8) HDD:
I recommend a 2TB drive. The price difference is very small compared to 1TB.
9) Windows 8 64-bit OEM
10) START8 ($5 from Stardock; bypass the new Start Screen and Charms.)
*Windows 8 is superior to Windows 7 except for the new interface.
11) CASE FANS:
- one or two low-speed INTAKE FANS at front
- one or two low-speed EXHAUST FANS
(Many PC cases have some. Many people forget the very important front INTAKE when building a gaming PC. Buy a case with one or add one. If possible, get one you can CONTROL but it can be hard to determine if your motherboard uses 3-pin Voltage or 4-pin PWM fans.)
SUMMARY:
Take your time and double-check all the components for compatibility. Read reviews for important parts like the PSU, Graphics card and Motherboard. Don't forget all the little things like a front intake fan (or USB3 on the front of a case).
Finally, don't forget the important MAIN CHIPSET driver etc from the motherboard support site (ignore the CD).
