Once again a big sale has caused a game to shoot up to the top of Steam's top 10 best selling games for the past week. This time Gearbox Software' shooter Borderlands, which had a 75 percent sale in the middle of last week, found itself at the number one spot (based on revenue). In fact two of the game's DLC mini-expansions, which were also on sale at 75 percent off this past week, made it on the top 10 list as well.

A two game S.T.A.L.K.E.R. bundle, boosted by a weekend sale, made it to the number two position on Steam's list this week. The full list is as follows:
1. Borderlands - Gearbox Software/2K Games
2. S.T.A.L.K.E.R. Weekend Deal Bundle - GSC Game World
3. Mafia II: Digital Deluxe Edition - 2K Czeck/2K Games
4. Mafia II - 2K Czeck/2K Games
5. Battlefield: Bad Company 2 - Digital Illusions/EA
6. Kane & Lynch 2: Dog Days - Io Interactive/Square Enix
7. Borderlands: The Secret Armory of General Knoxx - Gearbox Software/2K Games
8. Worms Reloaded - Team17
9. Fallout 3: Game of the Year Edition - Bethesda Softworks
10. Borderlands: The Zombie Island of Dr. Ned - Gearbox Software/2K Games

As we mentioned earlier today, Bethesda Softworks has launched a pre-order special for folks who wish to get the PC download version of theupcoming RPG Fallout New Vegas. Now Steam is not only offering the game for pre-order but is also putting three of Bethesda's previous games on sale this weekend only.

For this weekend, you can get Fallout 3: Game of the Year Edition for $24.99 (a 50 percent savings) You can also download and purchase Elder Scrolls IV: Oblivion Game Of The Year Edition Deluxe on Steam this weekend for just $8.50 (a 66 percent savings). Finally Elder Scrolls III: Morrowind Game of the Year gets its price cut by a whopping 75 percent this weekend on Steam. You can get the game now for a mere $5.

The long awaited launch of the Mac Steam client is now available to download, but it looks like Valve, at least as of this news post, has yet to go live with the client's Mac Game Store. Our sister site Joystiq reports that Mac users can still purchase games via the official Steam web site.

At the moment there's not an official list of games for the Mac launch of Steam although it's looking like it could be as many as 50 titles could be available for Mac users. Many of them will be able to be downloaded for free if users have already bought the PC version of the game via Steam. We will update this post when we get a definitive list of launch titles for the Mac client.

Update: Valve has now turned on the big switch to the Mac game store and indeed well over 50 titles are available to download for Mac players. You can check out the full list of games after the jump. One note: Torchlight is now on sale for both the PC and Mac for just $9.99.
