8800gts-640 to 4890 power supply Q

[SoiledBottom]

Hey Hey All

I just recently upgraded from a 19 inch CRT monitor to a 28 inch Hanns.G LCD monitor.

My video card is a 8800 gts 640 and my power supply is a Antec neo HE 550 watt.

Today I just ordered a http://www.newegg.com/Product/Product.aspx?Item=N82E16814161276. from newwegg.

Will my power supply be enough ?

What kind of performance gains should I expect going from a 8800 gts 640 to a 4890 ?

I play Titans Quest and Civ 4 mostly.

Also

CPU- AMD 7750 BE
MB-Biostar Ta 790GX3 a2+

Thanks in advance

Soiled

Hello and welcome to the forums
Yes your PSU would do the job,u will see a massive performance increase,if u played some more heavy games like Crysis,FarCry2 u would see the performance gain more

You are going to love the monitor. I went from a 19" to a 26" and gaming is SO much better!

The psu will be fine.

Overclock your CPU to keep up with the GPU.
