Hi all and thanks for looking.
My problem[/b][/u]
I currently have an Antec True550P and I suspect it might be the cause of the performance issues I am having.
The following is the original spec of my rig when I first got this PSU:
Athlon 3500+ Newcastle
6800 GT
Hitachi Deskstar 7200 Sata x 2 (Raid)
4 x 512mb Corsair C2 Platinum
Asus A8V Deluxe mobo
LGDVD drive
Antec True550P (550 watt)
XP Pro 64 bit
Performance was very satisfactory and I had no quarms with my system. Since, I have made the following changes to my system:
X2 4400 Toledo
Sapphire 1950 Pro 512mb
WD Raptor 36gb x 2 (Raid0) + Hitachi Deskstar 7200 Sata x 2 (Raid) making 4 drives in total
Performance, woeful to say the least. I noticed the difference straight-away, things were not as smooth and most noticeable was the stuttering that occured when panning in game (joint ops). I cannot pan 180 degrees in game without it stuttering. This stutter would be momentary but enough to put me at a disadvantage when in a shoot-out. Fraps show 40+ fps constantly but it does not feel sharp nor responsive.
FEAR just murders my system after 5 minutes, it starts to play like a slideshow.
I do not think that temp is the problem as I am showing no more than 57 Celius on my card when playing.
The only thing I can think is that my current spec is just too demanding on the PSU, especially the 12Volt rail and i am currently thinking of buying this PSU as the last effort to solve this problem before I swap my 1950 pro for a 6800GT!

Any help / input would be appreciated.
PS: The PSU states that it can pump through 30amps on the 12v rail which according to this should be sufficient.
