Best value graphics card 130-160$ range ?

easy, that is the 650ti BOOST or the HD 7850... the 7850 has more overclock headroom, and depending on the model should out perform the 650ti BOOST by a few percentage points in most models... but that said, they're really pretty close in their performance. Close enough that if you perfer Nvidia to AMD you won't notice the difference.

If you don't plan to SLi/xfire in the future Stick with the 1gb versions... these are both just slow enough you won't need 2gb of vram (if you do plan to xfire/SLi those cards, you should definately get the 2gb cards, that said, xfire is broken, so if SLi/xfire is in your future plans, get the 650ti BOOST, not the 7850)

The next step up in gpus are the 660 and the 7870... if you can find one on sale inside your price range hop on it.
 
650 Ti Boost .... nuthin else even comes close:

With the Radeon HD 7770 at $120, Radeon HD 7790 at $150, and Radeon HD 7850 above $180, Nvidia is rendering all three products ineffectual at their respective price points. With one swift stroke, the company engineered a hostile takeover of the $100-$200 market, increasing graphics performance at any given budget in that space.

single 650 Ti has 111% of the performance per dollar of SLI'd 650 Ti Boost and those two beat the 7970 Ghz and 680 in both performance and performance per dollar.

2 days ago the 2 GB version from MSI was $140 after MIR

$155 today http://www.newegg.com/Product/Product.aspx?Item=N82E16814127730

And SLI doesn't double ya GFX memory, so Id recommend the 2GB for 1920 x 1090 either way
 
except you can get the 7850 for 130 now... and it is just as good as the 650ti BOOST (at stock the boost is a little faster in some aps... but the boost has almost no overclock headroom, where as the 7850 is a great overclocker). And you're right, if you plan to SLi, get the 2gb version... otherwise 1gb is good enough.
 


PCpartpicker isn't the best website for finding deals. Amazon.com has hardware sales all the time that aren't reflected on pcpartpicker (i remember seeing a samsung 840 pro 240gb for $179.99 on amazon, where as pcpartpicker claimed amazon was selling it for $250, and it claimed the cheapest available was $240), and there are likely local computer hardware stores not listed. In my case there is a store called Fry's Electronics, which often has parts on sale for far cheaper then the lowest price you'll find on PCPartPicker or Newegg.

Just got a HD 7770 for $84 at Fry's Electronics... when i was there I nearly pulled the trigger on a HD 7850 (1gb) for $128

The moral of the story is dig deeper... there are usually better deals out there if you spend 30 minutes or so looking around before you pull the trigger on buying something.
