Buying New Laptop

I don't know if this is the right thread for my question so if its not please excuse my mistake. I recently bought a replacement laptop because my old one had an unfortunate accident. I reviewed many different laptops before deciding on the one I currently bought. Yet I am having very serious doubts that I have made a huge mistake. I am a advide gamer on a budget of about $600-700 tops. Now I understand that most capable rigs are well over 1,000 dollars and trying to find that balance between cpu and gpu is tricky when you don't have that kind of money. My old laptop was an Hp Envy 14 1110nr had intel i5-460 8g 640g 7200rpm with switchable ATI 5650 graphics.
Now even though It wasn't a beast with more modern games it held its own. I really never had a problem with anything other then me dropping it (that's how it died) it worked great up to that point. I have owned both a AMD processor and a Intel processor finding that overall the Intel was faster yet lacked a capable gpu since its integrated. The AMD one was considerably slower but graphic wise ran circles around Intel. So I went in looking for a Intel i5 or i7 but the problem was again the graphics, Intels hd series were bad compared to AMD's Radeon series, unless it was a dedicated card. After lots of searching I went with a HP ENVY TouchSmart 15-j173cl mostly because of what it had spec wise and the PRICE I paid $514. Spec wise it came with a AMD Quad-Core A10-5750M Accelerated Processor 2.5GHz up to 3.5GHz, 4MB L2 Cache Memory 12GB DDR3L SDRAM (2 DIMM) Memory Max Maximum supported = 16GB Memory Slots 2 user accessible Video Graphics AMD Radeon HD 8650G graphics with up to 6252MB total graphics memory Display 15.6-inch diagonal Full HD BrightView LED-backlit touchscreen display (1920x1080) Hard Drive 1TB 5400RPM hard drive with HP ProtectSmart Hard Drive Protection Network Card 10/100/1000 Gigabit Ethernet LAN (RJ-45 connector) Wireless Connectivity 1x1 802.11b/g/n WLAN Sound Beats Audio quad speakers and two subwoofers Keyboard Full-size island-style backlit keyboard with numeric keypad
I figured it was a steal for what it came with, I should mention that it was a refab from hp directly, brand new it lists for about $900 but I have NOT had any issues with it. After installing a few games BF4, watchdogs, NFS RIvals, Borderlands 2 and GTA I found that I can run all these games but on very low settings. I cant run anything 1080p but minecraft, I could care less about it being touchscreen nice little perk but I never really use it. What I have found is that this unit is slow very slow I feel like the Intel processor I had in my other Envy was faster then this one. Yet when I looked up the breakdown reviews of the quad-core (gamedebat.com) it showed that it was faster then my old Intel, all around better. Even though it recived favorable reviews I still feel that it struggles exspecially when I try to run multiple programs at the same time, this can be very fustrating.
Now my question is very simple this do I stay with this one or try to find something more suitable for my needs. I have till Thursday to return this for another one or a full refund after that I own it. Is there anything else you think might work better for gaming in the price range of 600-700 or should I just keep this one. It is going to be primarly used for gaming, movies, web use and minor word processing. Only requirments I have is that it has to be a laptop not a desktop, backlight keyboard and at least 15.6in screen would love 17.3 but not required. I really apprechciate any help that you can give me on this.
Thanks Jason
