DC 2.3 G5 worthwhile getting?

If it's cheap and the dual core, not the dual processor 2.3, it's a nice machine; I owned a couple of them and it's the fastest PMG5 you can get that does NOT have liquid cooling. The quadro will not work on the earlier dual processor 2.3 G5, of course.

 

Why do you advise against the DP model? I have one and it's not too far behind my Quad in what it can do?

If the price is right, go for it - it'll still cope well with modern web with TenFourFox and Leopard Webkit and you can watch HD video. I'd definitely upgrade the card though, if only to something with more VRAM - if you weren't gaming it's not a necessity but as you are....

 

2.3Ghz G5s are the fastest factory air cooled units worth picking up if the price is right heh esp if its a dual core 2.3 (DP ones are still good too) just a note no 2.3Ghz G5s shipped with a FX5200 and if this G5 does have one fitted then its not the original card and it would mean its a DP 2.3 with an AGP and PCI-X slots not a DC G5 which have PCIE slots and are the only G5s to take a Quadro FX4500

 

Can't use a Quadro on it. Also memory is faster and you can put 16gbs of ram in the DC 2.3 "late 2005" PMG5

 

Worth getting? That depends on how much you are expected to pay for it. $40, yup its worth it. $200, no its not worth it.

 

I guess nothing's crappy at old stuff. Price and passion matters...
Any G5 will do everything (PPC/Leopard/TFF/webkit plus video with CorePlayer) at it's best.
Same for old games...
Anything beyond that experiance is at +/- 200€ for >= core2duo Macs (but they won't go back to the roots)
Have fun...

PS: I nearly got a heart attack carrying a G5 to my car over long distance and heavy rain.... ha! it's physical presence is kind of unique. I'd go for YOUR G5 if I was you - the next G5 certainly is about >4000 miles away from you!
Just go & have fun!
