hello

i have recently bought an advanced dock for my thinkpad, and i would like to buy a graphics card for it
sadly there are some restrictions:
-the bus is only pcie x1 but has the full x16 length so any card can fit
-there are limitations in size too, something around this card: http://www.legitreviews.com/article/336/1/
-consumption must not exceed 50 watts (preferably stay below that at least 5-7 watts

currently i have a firegl v5250 in the notebook with 256 mbytes of ram (more specific here: http://www.thinkwiki.org/wiki/Category:T60p )
it performs rather well with older games, but newer games stress the gpu up to 90 degrees celsius, so i would like to save the gpu for mobile usage, and use only the docking stations video card
but it is obviously not a gaming card

i was thinking with going with the low end HD 4xxx 5xxx 6xxx video cards as the have pretty low price but i dont know if they can outperform the built in firegl despite the x1 pcie bus

thank you

i would like to go with the hd 6570, but sadly newegg is not an option for me since im not from the US
what other manufacturer's card is worth trying, a sapphire hd 6570 silent is available in an online store - or there are no differences?
so far i have good experience with HIS cards

another question is are there exact numbers regarding the power consumption of each card?
i have read that the 5570 draws about 43 watts and the 6570 even less, but i would like to be 100% sure because people had alot of problems with this docking station in the past by choosing the wrong card

6570 GDDR3 draws 44W/10W, with fan less models knowing another 1-2W off.
Sapphire is nice too. Where are you buying from?
