Good Points: Fast! Brilliant Graphics Quiet Big Fan for cooling and built in exhaust system Stylish design Easy to use drivers/software
Bad Points: Very large card Temperatures can be HOT Power Hungry Drivers are a bit touchy
General comments: The 'ATI Radeon HD 2900 XT 512mb' graphics card is currently one of the top of the range cards and is brilliant! Graphics are brilliant and I can set game settings to "HIGH"!, Battlefield 2142 looks fantastic, combined with 2GB of RAM and 64bit OS and it copes with a lot! (All depends on what other bits you have in your system) It's quiet when on idle, but the fan 'should' kick in to Fast speed when you begin pushing the card during gaming, this forces air over the chipset and with its built in exhaust system, instead of forcing the hot air out of the card and around the inside of your system, it forces the hot air out the back of your pc case, making the inside air cooler. But due to the card large cooling design the card is rather large and one of the most heaviest cards I have ever come across, not ideal for small cramped computer systems (check before you buy!), It has a nice design (from Sapphire), and makes any case look the part. Being ATI you can have two of these cards running using 'Crossfire', although I haven't tried this, I think that even myself with a large computer case would struggle to fit two of these monsters side by side - One of the problems being that due to their size the air space required to cool the top card is restricted and will eventually lead to overheating issues! - To overcome this some have forced apart the cards just enough to allow room, but put strain on the card contacts and the motherboards PCI-e slots, which is NOT recommended. (Bit of a concerning oversight by ATI!) Although early days this card is stated to become better given some more time when Direct X 10 is unleashed, haven't read into this but I'm looking forward to it. Regarding POWER... yes this card is exactly as I have stated... HUNGRY... The minimum requirement is around 600W, of "Stable" power (and that's just for the one card, you will need around 800W odd for Two cards to run. I used the word "Stable", due to the fact that it is most commonly believed that a 600W device will run on a 600W Power Supply Unit (PSU), unfortunately this is not the case as most PSU's advertised will run at 600W but that is their maximum output and most can not sustain such an output for a long period of time, instead they will usually run at a constant output of at least 80-100W below their stated maximum (I.e. a 600W PSU will run at around 520W odd), I may be wrong but this is the research I have been able to find). I found this out the hard way after blowing one expensive £100 PSU, another fact to include is, although the device you are going to power will require 600W, you have to include all the other hardware you have in your system,(E.g. Hard Drive, Floppy Drive, DVD drive, Motherboard, Sound Card, Fans, Lights, Multi-card reader, etc) all of these items require a set amount of power! After my expensive mistake I opted for an 800W PSU, although being 200W more than required I left myself enough leeway to allow for my other items in my system and a bit of Wattage to spare. Enough about power requirements, now on to HEAT, this card does pump out the heat and in a small PC room it can help to do a bit of energy saving too, it does come in handy to pump out the hot air to heat your room, It runs at around 50
