Lifehacker Guide with GA-EP45-UD3P Motherboard in OSx86 10.6 (Snow Leopard) Posted November 14, 2009 As for that particular Gainward card, read below... Since Stellarola updated the installer to PC EFI v10.5 (Thank you Netkas), the bootloader now detects the Nvidia card you are using beyond the 8 & 9 series of cards with support of the GT200 based cards. This does not require any kind of modification or special installers anymore. Now keep this in mind, only the cards available as of when PC EFI v10.5 was released, are going to be supported. I know that Nvidia does have some others coming out that are revisions of the current GT200 die, mostly a shrink in die, but they also support DX11 (meaning a physical change in the GPU). They are the only ones of the GT200 series that will, I do not know the card identifications but as I am aware, all GTS 250/260/275/280/285 are supported. I think the GTX295 is recognized as 2 separate cards so its not worth that purchase. I am using the GTX275 simply because its the same chip as the GTX 280/285/295, 240 SP's and 32 Rop's, with the only difference being the memory size, and bit of the memory architecture (defined by the size of memory for Nvidia) and the price. Got mine on newegg for $230ish... You can definitely say I know my graphics cards as I follow Nvidia closely, I am a die hard fan! Please do not take what I am saying as absolute for every install. The card I have is by EVGA and the reason for that is they stay close to the Nvidia reference designs. This means you will have better compatibility as some Nvidia partners can take a card reference design, and change it so it suits their needs and what they want for an end product. Typically XFX, EVGA, BFG (unless its very radical) and ZOTAC use the reference designs and can swap the cooler, or make a better one for the OC versions of the card. Use at your discretion but as far as the V3 of the installer is concerned, it worked flawlessly off of a clean/fresh install with successful update to 10.6.2 with both DVI ports working on my dual Cinema Displays. Also, since my original Rosewill PCI NIC died, I installed a Netgear GA311 and it worked right out of the box. I disabled the onboard ports just to play it safe, and it has full Bonjour support! Wow, thanks for that! Would you happen to know what space in the case I need to install one of these (Say 275), I understand the lenght is usually 27cm but does that include the mounting bracket that sticks out as I don't think I have room in my current case otherwise?
