Two x1900 cards

This should help. Check out page 65

Wow, they are pricy! Maybe it's because so few cards were made for the PCI-E macs. I use a 6600 256 mb card for my second display. I got a flashed 7800 GTX off of eBay that works really well for my main display. There are surely other flashed cards, perhaps some for less than the 1900.

Yes, according to the manual, and for me, my experience confirms it. My 6600 is actually in my 4X slot to give the GTX some breathing space and it works just fine. And I wonder just how much speed is given up by not putting one in the full slot. As you said, though, for our purposes, I don't think it matters all that much.

Thanks for the feedback! 🙂 If you do go hunting for a 7800 GTX, try "local338" on ebay. They were great to deal with and though the card was refurbished (maybe because it was flashed), it looked mint and has run just great. Have fun, Stygi.

They were great to deal with and though the card was refurbished (maybe because it was flashed),

Exactly. Because it has been installed and "used" during the flashing, it can't be sold as a "new" card, due to the over abundance of out of work lawyers in the US........... 😉

Lol 🙂 ... Yeah, I had hoped that was the case. Sure seemed brand new to me.

Yeah, China (not that that's a terrible thing) but Hong Kong to be precise. If you go that route say Hello to Wai for me from bienchat. He was a heck of a nice guy. There was some back and forth between us as I'd never installed a card like that before and he was unfailingly decent and helpful and, it seemed, always there. They take their business very seriously.

I think this is the page Japamac made me look at:

He said he'd help pay for it but I've yet to see any cash...

(J/K Japamac 😉.)

Thats great, Stygi 🙂

A full house indeed. Might be a good time to invest in the application "Hardware Monitor" as well:

I just had a Dual 2.7 that seemed to constantly run too hot for its own good. Since getting this one I've become obsessive about temperatures in general and I use Hardware Monitor quite often to keep an eyes on things. Perhaps with all slots taken on your machine it would be a good idea to check the cards temps every so often. I'm sure you don't want them to go prematurely. HM is just a good app in general that reports on a lot of things. The best of its kind, imho, out there.

Good luck with your new set up. I'm sure you'll be very pleased with it.

Take care,
Steve

Hardware Monitor costs some money too but I've found it to be worth it. I used to use iStat Pro but I found its CPU readings to be unreliable. HM does show GPU temps, and quite a few others, and quite a few other things in general. I've bought a few things from Dr. Bresink even the CPU speed menu. Yeah, I balked at paying for that also, but I got tired of the hassle of changing power settings myself all the time. I change them quite often too. And I also run at highest or lowest only, never automatic. CPU Speed Menu gives you several different ways to set it up. I have mine set to only show high and low. Its pretty handy and for 8 bucks, eh, I came around to the idea and don't regret paying for it.

Nor do I regret buying Hardware Monitor. The guy works right off of Apples Specs and his products are solid and accurate. But the real clincher for me is the customer service. Dr. Marcel Bresink actually answers all the email sent to him himself and quickly at that. He is really knowledgeable about all things Mac and has informed me of things that I can't imagine finding out about anywhere else. Granted he does seem to have a stern way about him and probably doesn't suffer fools gladly, but again, the guy stands rock solid behind his product.

Stygi,

I hate to tempt you any further, but...

I get email from these guys (at my request). I've bought a lot of stuff from them and they're great to do business with so I like to know what their latest deals are. Anyway, just got another mailer from them and noticed this: http://eshop.macsales.com/item-maillist/Other%20World%20Computing/42DDR2PAIR4G/? source=hdb0919

They are going for 12 dollars less than I paid for them a month or so ago.

Just thought I'd give you the nod as you seem to be as performance oriented as I am. I swear I won't tell you how fine the Velociraptor is though. 😉
