Hi Guys!
In need of 2nd opinion from anyone. Anything is appreciated.

My current PC:
- Amd X2-4800 (socket 939) on MSI K8N platinum (Not O/C'ed, stock speed)
- XFX 8800GTX 768Mb (Not O/C'ed, everything in stock speed)
- 2GB DDR pc3200
- 3 x SATA HDD (80Gb & 160 Gb Seagate; 74Gb WDC Raptor 10k)
- 1 IDE DVD-ROM
- 1 IDE DVD-RW
- using 3 8cm fan (not high performance)

I've been planning to upgrade to:
- Intel E8400 (want to do 3.6 GHZ)
- DFI Lan Party (either P35 or P45 MoBo)
- 2 x 2 GB OCZ PC-8000 DDR2
**Everything besides those 3 above is still the same (GPU, HDD, Optical, etc)**

My Current PSU : Thermaltake Toughpower 550W (been using it +/- 3yrs)
---------------------------------------------------------------------------------------------
I already did some research on the web and using Extreme PSU calculator, and i found that my PSU should be adequate since my old PC consume more than my future one. <---- IMHO

The question is should i stick with my old PSU, or should i search for a higher wattage (with the same quality of course) ??? Considering that my PSU is already about 3 years old +.

Should i test my old psu first? (doing some stress test on the pc?)

Ok Guys, thanks for your time 2 read this, i'm sorry if i got a bad english :) 

Thx a lot!!!!

I have a newer modular TT 550 with 16A on one rail and 17A on the other. I am running a Phenom II 940 OC to 3.2Ghz. 8 gigs of ram. 7 fans, and a EVGA 260 core 216 plus the HD, dvd etc. I can run Prime 95 and folding@ home at same time--No problems.

Well, as you can see from the posts, you will be fine.

Quite a few people think they need a lot of power. That is usually not the case, especially if one is not a hardcore gamer or serious overclocker. Tom's Hardware just did an article about video cards and power consumption. I already knew my own video card did not require a massive amount of power. What surprised me in the article was just how little my video card required even under load.
