I realized there are a million posts on video cards, so thanks in advance to anyone willing to reply and help me with this issue! I've read multiple forum posts and looked all over the net, so please don't think I'm just prematurely posting on this issue. And, I have no problem admitting I'm kind of ignorant on the whole thing as well. Problem: I have a mac pro that I want to replace the video card in. Here are my specs (I'll include as much as I can, I figure overkill is better than under): Model Name: Mac Pro Model Identifier: MacPro1,1 Processor Name: Dual-Core Intel Xeon Processor Speed: 2.66 GHz Number Of Processors: 2 Total Number Of Cores: 4 L2 Cache (per processor): 4 MB Memory: 2 GB Bus Speed: 1.33 GHz Boot ROM Version: MP11.005C.B08 SMC Version (system): 1.7f10 ---- ATI Radeon X1900 XT: Chipset Model: ATY,RadeonX1900 Type: Display Bus: PCIe Slot: Slot-1 PCIe Lane Width: x16 VRAM (Total): 512 MB Vendor: ATI (0x1002) Device ID: 0x7249 Revision ID: 0x0000 ROM Revision: 113-A52027-202 EFI Driver Version: 01.00.202 Displays: Cinema HD: Resolution: 1920 x 1200 Depth: 32-Bit Color Core Image: Hardware Accelerated Main Display: Yes Mirror: Off Online: Yes Quartz Extreme: Supported Rotation: Supported Display Connector: Status: No Display Connected ---- This is my second Radeon X1900 XT card. Both have performed well, but this one is slowly dying in the same way the other did (glitches, asking for reboot, and extreme noise). 1. I am still uncertain of what cards are compatible with my system. I would like to stick with ATI over Nvidia, just due to past experience ( also I hear ATI is now being rebranded?) 2. My main concern is noise. I want a silent card, or a card that I can add an aftermarket solution to to silence. 3. I don't really want to "flash" the card or do anything that will be difficult or cause bugs in the future. 4. My budget is around $180. So, I'll get the best I can for around that. Any advice or clarification would be SO MUCH appreciated.
