Will I have enough power?

[Hariibros]

In light of the recent gtx 780 price drops im am contemplating ordering one. I have a 650w PSU and the following components;
Amd FX 4100 cpu (non overclocked)
7200rpm Sata HDD
Dvd/cd reader and writer
a fairly cheap gigabyte m-atx mobo
200mm case fan
120mm case fan
8gb Crucial ballistix sport ddr3 ram

And the current gpu is a gtx 660.

My final question is will I be able to use a gtx 780 in replace of the 660?

what brand is the power supply? its important to use a good quality psu. also i think the cpu will be a bottleneck in games

As long as it's a decent power supply, yes you can use it with no problems.

The psu is an 80+ bronze rated OCZ modular psu

you will be fine with the upgrade. its a good quality psu. nvidia reccomends 600w+

The OCZ ZT is a very good unit. You are fine.

The above poster is correct about bottlenecking though. Trade out for an FX 8320 or 8350 if you can. The 4100 is a terrible gaming CPU. Even overclocked to 4.5Ghz it's still pretty weak.

You will want to pair a high end card like the GTX 780 with a CPU from the top 2 tiers.

My 2600K at 4.5Ghz is perfect with my EVGA GTX 780 Superclocked. I can max anything at 1920 x 1080.

A lesser CPU will hold the card back quite a bit.

Ok finally if I upgrade to the fx 8320 will I still have enough power or do you recommend dropping the gpu down to a gtx 770?

enough power
