aaaaah, thanks guys.

encouraging input. it sounds like i may still have some options for this old box of mine.
so, let me get this straight...
Silat recommends the ATI X850X at $349.00...
38RUK, you're recommending this
Sapphire card as a less-expensive alternative. is Sapphire a manufacturer that builds the generic version of the card, basically?
eagl recommends the GeForce 7800GS at $349.00--comparable to the ATI X850X.
again, newegg appears to be selling a generic version of the card
here for $299.00
Roo is recommending the
Crucial X1600 at $300. if I purchased this card,
should i expect overheating issues considering my Dell (P4, 2.4GHz) has room for only 1 fan?I apologize for calling the newegg products generics. currently lacking a better word for it.

NOTE: I don't mind spending the $300-$350 if it's a safer bet.
Could really use your input re: the reliability of mainstream vs. generics.[/color]
Thank you, gentlemen.
The Crucial card sounds cool. But, it requires a 350W power supply. My stock power supply = only 150W.
