"What is missing from your Mac? What are the performance bottlenecks? What do you need to know before you take the leap and buy a new Mac?"

Missing From the Mac Pro
- SLI or Crossfire support -- High-end Windows PCs offer the ability to link to graphics cards to form a "dual processor" GPU -- too bad the Mac Pro doesn't support this capability
- At least one PCI-X slot -- We are thrilled to have high speed PCI-Express slots, but instead of making all four slots PCIe, why not go with one PCI-X and three PCI-Express slots? That way, consumers with a significant investment in PCI-X cards don't have to toss them in the trash and start over with PCI Express versions.
- Full 32 lane PCI-Express bus -- The bus controller chosen only supports a total of 26 lanes. And though you can install up to four graphics cards, only one will be running at 16 lane speed.
- Dual channel FireWire 800 -- Though there are now two FW800 ports, they both share the same data channel along with the USB 2.0 and FW400 ports. That puts a crimp in transfer speeds attainable by those slick FireWire 800 RAID boxes.
- More advanced graphics card choices like the GeForce 8800 Ultra or the Radeon HD 2900 XT
- An external SATA port
Missing From MacBook Pro 17" and 15"
- An advanced model like the AlienWare laptops that feature dual boot drives, upgradeable GPU, and SLI mode for dual GPUs.
Missing From MacBook 13"
- "Real" GPU -- The Intel GMA950 lacks its own VRAM and runs Core Image effects and OpenGL 3D much slower than the MacBook Pros.
- FireWire 800 port -- -- external storage has to use FW400 or USB2 ports, neither of which achieves the full potential speed of 7200 rpm drives.
Missing From Intel iMac
Missing From Mac mini
- "Real" GPU -- The Intel GMA950 lacks its own VRAM and runs Core Image effects and OpenGL 3D much slower the Intel iMac.
- FireWire 800 port -- would be nice to have for booting from an external, fast 7200rpm 3.5" drive enclosure; or how about an external SATA port?
Missing From the iPhone
Missing From OS X
- True WYSIWYG for Apple displays -- higher dots per inch is good but it makes everything look smaller than reality -- this can be fixed if Apple will implement the Core Image code that allows users to scale the resolution -- see the OS X Tiger Quartz Debug tool's resolution palette for a demonstration of this. This should become the norm when OS X Leopard is released, according to Apple's developer overview (see paragraph on Resolution Indepenence). Apple is so serious, they have patented the technology.

- Backlit Keyboard for Desktops

For refurbished, reconditioned, open box (as well as new) G5 Power Macs, check with Small Dog and Power Max. Check also at the Apple HOT DEALS section for factory refurbs and other specials.
Some of you have asked which "older" G5 Power Mac models are most desirable. Whether you buy a refurbished or used G5 Power Mac, I recommend getting a model with 8 memory slots, 100/133MHz PCI-X slots, and 600W Power Supply. The table below gives the model number, etc., of these most desirable G5s.

All other models have only 4 memory slots, 33MHz PCI slots, 450W Power Supply, and slower frontside bus speeds. If you can't find the model you want at Apple's Special Deals page, Small Dog's site, or Power Max's site, go to Froogle.com and search on the model number.

WHERE TO BUY VARIOUS GRAPHICS CARDS FOR YOUR POWER MAC and MAC PRO
For your Mac Pro, you have the following 16X PCI Express (PCIe) options:
The GeForce 7300 GT (16X, 256MB, dual-link DVI + single-link DVI port) is the default. We recommend the Radeon X1900 XT (16X, 512MB, two dual-link DVI ports) as a CTO option. It's much faster than the GeForce 7300 GT and just as fast as the expensive Quadro FX 4500. According to Alias/Autodesk, the X1900 XT is the only graphics card without limitations when using Maya 8.5. To custom order your Mac Pro with the Radeon X1900 XT, go to the Apple Store and click on the Mac Pro graphic.
If you didn't order the Radeon X1900 XT with your Mac Pro, you can order the Radeon X1900 XT as an aftermarket kit for your Mac Pro, go to the Apple Store and click on DISPLAYS in the left margin or do a search on "X1900."
NOTE: Mac Pro PCIe graphics cards will not work in Power Mac G5s with PCIe slots -- and vice versa. Nor will Windows PC PCIe graphics cards work in the Mac Pro.
Graphics Card Options for the Dual-Core or Quad-Core G5 with 16X PCI Express slot:
The best option for your Dual-Core or Quad-Core G5 with PCIe slots is the ATI Radeon X1900 G5 Mac Edition released in November 2006. You can buy it directly from ATI's Online Store for $299 (with "trade up" allowance).
It's also sold by Small Dog Electronics and Other World Computing.
The following cards only work on a G5 Power Mac with 8X AGP slot:
The "G5 only" Radeon X800 XT Mac Edition (8X AGP, 256MB, ADC + Dual-Link DVI port) is available from ATI Online Store, Apple's Online Store, Buy.com, Other World Computing, and Small Dog Electronics. (The MSRP is $299)
Apple's Online Store is no longer selling the GeForce 6800 GT or Ultra, which had Dual-Dual-Link DVI ports (for two 30" Cinemas).
The "G5 only" Radeon 9800 Pro Mac Special Edition (8X AGP, 256MB, ADC + DVI port) is no longer made by ATI.
The following cards work on both the G5 Power Mac (8X AGP) and G4 Power Macs with 2X or 4X AGP:
Other World Computing has the new ATI Radeon 9800 Pro Mac (2X/4X AGP, 256MB, DVI + VGA ports) graphics card in stock for $259. ATI has it on their Online Store for $249. The SKU number is 100-435058, in case you want to make sure you are getting the right card.
