Need help finding best PCI video card for gaming

[winged]

i own a dell dimension 2400,
SPECS:
Intel Celeron 2.4 GHz
1.5 g of ram
currently equipped with a GeForce 8400 GS
and i replaced the 200 W supply to a 380 W supply

in battle grounds like AB or WSG ill get 25 -30 fps which is good but i want to raid 25 man instances where my frame rates drop to about 8-15 fps and i want more than that.

ive allready looked at some upgrades and i believe from what ive seen that this GeForce 9500 GT in PCI format is best in slot for my computer at the moment

(its on newegg, i cant post URL's =/)

please correct me if im wrong and link any better video cards for PCI slot computers.

NOTE: i want a gaming video card thats best for PCI

Next my guess is the 9400gt or 8600gt. The 8600gt are only sold at certain places in the us.

I would say 9400GT .. its best.

The 9500gt is clearly the best one
