I heard the cooler is good 

hd5770 for more satisfaction and greeny..

I see..so 5750 good already lo..but 5770 is better choice if u wanna keep ur bdget then..

ur monitor 1920x1080? if yes at least get a 5750

Please use Windows 7 la.. for DX11

i also interested on 5750 vapor x but somehow i admire ice q version from HIS .but HIS 5750 dun have iceq version,567o got  

ongdandy, XP only supports up to 9. DX 10 and 11 is in Win7.

For 1280 x 1024, HD 5670 will be fine.

Playing single player SC2 on Win XP with a 1920x1200 monitor, the HD 5670 is smooth at low quality graphics, and a little bit jerky on medium quality and it sometimes complains about memory issues (not sure what) but is playable. With multi-player, the game can get badly lagged when there are a lot of units, even at low quality graphics - not sure if it a GPU, CPU or network problem.

If Sapphire 5750 Vapor-X is within your budget, might as well get the normal cooler Sapphire 5770, only about RM50 more expensive.

If you are able to go to Low Yat Plaza due to where you live, PC-Zone is selling Powercolor 5770 PCS+ for RM555 (as from 10/8/2010), that only RM5 more than the normal cooler Sapphire 5770 (RM550).
PCS+ is the equivalent to Vapor-X in terms of these "special cooler"sort of to speak...or properly spoken: 'non-reference retail coolers'...

The 5750 'Vapor-X' version is a bit gimmicky because for low-mid end cards, such cooler is unnecessary since the 5750 is a cool card even with the reference cooler (the stock normal cooler)
So you either get the normal 5750, OR save a bit and get to be very happy to own a 5770. 
Alternately, you can find 2nd hand 5770 at Garage Sales...
