Which of these two cards is better and has more features?   I only play Microsoft flight sims and would like a card that doesn't consume too much power.  A mainstream card.
 
Visiontek  X1650PRO  256mb ram,  128 bit, DDR2   or    
EVGA 7600GT  256mb, 128 bit DDR3

 
 
Are you looking at AGP cards? Please give us some detail on your current machine before we can answer that.

I built my own computer with an Asus P5K-E motherboard,  E6750 CPU,  2gb OCZ 800mhz ram,  320gb hard drive.  I plan on using a 22 inch monitor.  System is not overclocked nor will I overclock.  Everything running at stock.   I'm looking for PCI-Express video card that is energy efficient, mainstream  and will run flight simulators and the occasional game like Call of Duty 4.  

8800GS is your card hands down.

What is your price range?  You might find a better performing card for a little more money.  Or are these 2 card availible at local brick and mortar store?

What are  your options for purchasing a card? You are better off ordering online. The prices are by far better.
 
You can get an 8800GS for $100 after rebate.  Next would be a 9600GT, then 8800GT, then 8800GTS, then 9800GTX. What is your budget? on a 22" I would recommend a 8800GT or above.

I bought the Visiontek X1650PRO from Frys.com for $20.00 after rebate and a EVGA 7600GT 256mb, 128 bit, DDR3 for $25.00 on Ebay.  The card is brand new.   I didn't want to spend too much since I mostly browse the web but would like to be able to play some of the newer games once in a while.  As far as a budget I'd say about 100 dollars tops.

The 7600GT is better than the 1650Pro.  So if you have to choose one of those, that is the one you want. You can play a couple games maybe on low depending if you keep the 1680x1050 resolution.  
$100 will get you a 8800GS after rebate which would be MUCH better.
