Do I need more power?

[dukefanmu]

My current setup:
Q6600 running on an Intel motherboard (will not allow overclocking)
4 gigs DDR2 800 mem
2 DVD+RW IDE drives
2 SATA 400 gig hard drives
Sapphire 4890 1 gig vid card
2 80mm case fans
Generic card reader
25.5 in Monitor running at 1920 x 1200

Currently I am using an Antec 500 watt psu. I just upgraded to the Sapphire vid car and new monitor. Should I buy a higher wattage psu? Crossfire or SLI is not an option with my motherboard. I use the pc mainly for gaming and I like to turn up the graphics quality and resolution as high as possible. Also, is my current CPU bottlenecking my system or is it still enough for now?

500 watt Earthwatts ? It's enough.

My PSU is an Antec Smart Power 2.0. It is a few years old.

Generally a high quality 500 - 550 watt power supply can easily power any single video card made. I'm not familiar with the Antec Smart Power series.

I don't trust them after a few years, I've replaced 3 of the 450 watt units that were just over 3 years old.
