I am planning to upgrade the ati HD Radeon 5750 that came with this system 2 years ago to a gtx 770 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814125462 specifically) I do have a few questions though before I actually buy the new card. Main question is if the card will be a major upgrade to my system. Here's the plan:

I want to eventually get around to building my own sweet gaming setup to play games like Crysis, Bioshock, and WoW at max setting but would like to be able to use the parts as much as possible before i finally amass the full sum of money I will need. I plan to use the 770 in my current system before moving it to the new build. Is this plan viable? ready and willing to spend ~$470

Plan to be running 3 monitors(1 23 inch(1920x1080) and 2 20inch(1600x900)) so I figured that the 4gb version of the 770 was much more optimal.

My cpu is an i7 870, will buying a new card change my system bottleneck from my gpu to my cpu?

I'm sure I'll come up with some other questions as answers come in but any help is greatly appreciated!

system specs

Gateway FX6840
Windows 7 home premium
intel i7 870
8 GB ram (sorry don't know brand)
ati HD radeon 5750 1gb
650W psu




 
Solution
IMHO decent 650w PSU should have 50a or more on the 12v rail or if it has multiple rails(which im not a big fan of) a combined power of ~600w on the 12v rails.

it is a quad core 8 thread chip so i think you will be fine

you can easily run three monitors but I am assuming you will only be gaming on one. If this is true then you are fine.

the brand of your ream does not matter but if it is 1600MHz ddr3 then you are fine there.

I think the 770 is about the pinnacle of 1080P gaming and I would think that you would be set for a while.
