Someone Please Help!
I really want to get a nice GPU upgrade and had my sights set on the EVGA GeForce GTX 660 Video Card
- 3GB GDDR5, PCI-Express 3.0 (x16), 1x Dual-Link DVI-D, 1x Dual-Link DVI-I, 1x DisplayPort, 1x HDMI, DirectX 11, SLI Ready, Dual-Slot, Fan (copy pasted from tigerdirect.com)
Am I going to be able to use this? Also, why is there like 8 different versions of this and each have a different price. I'm pretty lost in all this I apologize for the stupidity. What do I do? It says it has a minimum PSU wattage requirement of 450watts and my unit has 500watts.

I have an Acer Predator G3620:
Operating System: Genuine Windows® 7
Processor: 3rd generation Intel® Core™ i7-3770 processor
Graphics: Discrete card support for high-end NVIDIA® GeForce® and AMD Radeon™ graphic cards
Microsoft® DirectX® 11
I/O ports
Front:
Multi-in-1 card reader
Two USB 2.0 ports
Two USB 3.0 ports
Headphone and microphone line-out jack
Rear:
Four USB 2.0 ports
Two USB 3.0 ports featuring power-off USB charging
PS/2 keyboard and mouse ports
Three audio jacks
Ethernet (RJ-45) port
D-sub VGA port
HDMI® port
I/O expansion: PCI Express® 2.0 x16 slot
Three PCI Express® 2.0 x1 slot

So this GPU will work in my PC? Could you possibly tell me why there are many different units of the same model?
Here is where I am ordering from so please follow the link to tigerdirect and see for yourself. Thanks again!

The 760 was released today and put a hurting on the 6 series and with you not being able to overclock the 3770 it would be fine with that psu.

So this is a better card? It's not even more expensive, weird. I'm a total dummy when it comes to this stuff I just want to pay for it and install it and it just work nice. What makes this better than the 660 if you dont mind me asking?

760 is almost 25% faster then a 660 in BF3. The 760 is the new bang for the buck card under 250 dollars

I am also buying a GTX 780 which was PCI-E 3.0 whereas mine is PCI-E 2.0, so there was written (In the description) That hey are compatible with 2.0 and 1.1 also. So there are many chances that it may work. If you have a lot of money, buy another PCI-E 3.0x 7 slots Motherboard. Well if you don't have that kinda money, it will work on PCI-E 1.1 as its written in the description.

Intel God you seem to know your stuff...

Could you take a look at my thread and see what you think?

Andy, you may also need a compatible CPU and Motherboard to use this PCI-E 3.0 and GDDR5 Memory. I am using Intel Core i5 2310K and unfortunately it doesn't support PCI-E 3.0 so I'm running slow. Sill I play Need For Speed Rivals and Assassin's Creed IV on 1366x768 and everything else Ultra High. PCI-E 3.0 Would be even faster, something which I've not experienced....
