Alienware X51 RC1 GTX 555 OEM Upgrade

Hello, I'm trying to upgrade my Alienware X51 RC1 GTX 555 OEM GPU to something better. I've been searching for days and have not found a clear and safe answer. I have a 330W PSU with the following specs bellow. I was told that I could upgrade to the GTX 660 and I'm wondering if there are any other cards I can upgrade to that are better. Also when I searched for a GTX 660 I found such cards as a Evga GTX 660 3gb FTW and SC etc. Can someone please give me some of the best options that will not overload my system or cause me any problems? I've talked to multiple different Alienware support reps and all of them had different answers.  


Processor Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
Video Card 1 NVIDIA GeForce GTX 555
Video Card 2 Intel(R) HD Graphics 4000
Memory 16 GB

Zach, there are a couple of threads in Dell Community Forum that should be helpful. 

Here are some links that may be helpful:

Alienware X51 Mods & Graphics Card Upgrade BF Case Discussion - Alienware Forum - Alienware Club...

And, I believe this same mod could work for your X51 if you need to power a more potent GPU than a GTX 660... [Tutorial] Dual 330W AC Adapter Mod

I don't have an X51, so I am not following that topic closely. From what I understand the GTX 660 is not a problem and if memory serves me correctly some have even upgraded to GTX 760.

7700K @ 5.2GHz ● GTX 1080 SLI ● 17.3" QHD 120Hz G-Sync ● 64GB DDR4-3200 ● 780W AC Adapter

7700K @ 5.0GHz ● GTX 1080 ● 15.6" FHD 120Hz ● 32GB DDR4-3000 ● 330W AC Adapter
