Performance Bottleneck?

[Steve Watford]

MSI K9N Neo-F nForce 550 AM2
Sapphire X1600 Pro 512MB DDR2 AVIVO TV-Out/DVI (PCI-Express)
AMD Athlon 64 3800+ 2.4GHz (Socket AM2)
G.Skill 2GB DDR2 GA PC2-5400 (2x1GB) CAS3 Dual Channel Kit

Im thinking that the GFX card is the bottleneck, what do you think, all are at stock clocks etc. Overclocking the GFX will probally make the bottleneck lessen slightly, but probally not all that much i suspect.

Any comments?

X1600 Pro is 6600 GT area of performance (less than actually), so yes, it is most definately a bottleneck. New graphics card will really boost your rig
