when/t to pc world go a new psu 400w had to take it back do not work . so had a 350w from them put it in tower put asus gt610 in loaded farcry 2 3 mins red hot turn off pc remove power pack put my own 250w back in as you say that card will run ok on 250w/s have not put the card back in yet but i think i will give up on farcry2 .
I have to underclock my 610 on my 280w PSU just slightely to around 731mhz for it to not freeze, but it depends on how much power the rest of your pc is using.
I quite surprised by the power of it though, able to run S.T.A.L.K.E.R shadow of chernobyl and Prey no problems at around mid settings.
relating back to the original question here is the list of games I've ran on it.
S.T.A.L.K.E.R SOC & CS
Conflict Global Storm
Conflict Desert Storm
Age of Mythology
Age of Empires 2
Age of Empires 3
GTA vice city with mods in HD.
Vietcong 1 & 2
Mech Commander 2
Final Fantasy VII
Final Fantasy VIII
All of these games work at either Medium to Maximum settings else I wouldn't play them on the pc (Id just get the console version)
really it depends on the age of the game, The driver support and how well the game is optimised, I saw a video of someone playing Farcry 3 on one at respectable settings, either they were lying or had a few of them overclocked in SLI cause the reccomended Card for Far Cry 3 is a GTX670 (around £260) as its quite a graphically demanding game. (worth noting though for anyone wanting to play Farcry3 owning a 600 series card, the latest drivers from the Nvidia website apparantly increase your cards ability to deal with the game by up to 40%)
