What graphics cards should i get for decent gaming?

hi, I am currently using a 4670 to play all of my games: Batman arkham asylum, both crysis', Need for speed shift, Call of duty modern warfare 2. I currently have a generic psu but am going to upgrade to an ultra lsp model but i noticed they only have 2x 6pin, if i buy an adapter for 6-8 will it cause any problem like a molex to 6pin would? Also i wanted to know what graphics card would be best for me i currently play almost all of those games on high settings batman i can max crysis i put on high (not ultra) lower resolution 1280 X 800 and need for speed on medium because it runs horrible somehow. so for my resolution of 1400 X 900 native what graphics card would be suffice to run most games at max? im looking at 4870 or 4890 but i dont exactly want to spend the extra $50 for what i would tihnk of maybe 5fps more at my resolution. i would liked to be able to max all of those games except crysis since i know most cards cant. Thank you for your help

Adapters for 6-8 pins should be ok if your PSU has enough juice.

Get the 4870, it should do fine. I have one and can play Crysis at Very High w/ at AAx2 at 1280x1024

Or you can shell out $170 for an equally performing dx11 card 5770, or the same amount for a 15-20% better dx10.1 4890

is it a good idea to instead way until early january hoping that the gt300 comes out at the $600-700 range and assume that instantly ati would drop their price on 5970 by like 100 which would more than likely force the price of their other cards to drop down a fair amount.

Since you listed the 4870....my assumption is you will be in the $150-$200 range. At $155, the above gives tie for 1st place to:

ATI 4870 (DX10)
nVidia 260 (DX10)
ATI 5770 (DX11)

I'd lean to the 5770 if you don't upgrade graphics cards very often....say if you think you won't upgrade till after XMas 2011, the DX11 may be the better choice because of it's DX11 compatibility. No one knows if DX11 will be a factor at this time,... DX10 was a complete dud but we're all hoping that DX11 beings something to the table.....only time will tell. Going for DX11 now future proofs you a bit come 2012 if DX11 does in fact deliver something to be excited about.

On the other hand, since you listed Batman, as they put it in this article, PhysX is a feature certainly worth considering:

http://www.tomshardware.com/review [...] 65-11.html

"Turning on PhysX isn't necessary for gameplay, and you'll never miss it if you don't see the effects. However, when PhysX is enabled, it adds superlative nuances and really creates some “wow” moments. The chunky explosions, cloth effects, paper, fog, and environmental detail enhancements are very cool.....the eye candy is a lot of fun to watch. Once you've turned it on, it's not something you'll turn off if your hardware can handle it."

The 260 has more than enough juice to handle your resolution w/ PhysX. At 1920 x 1080 tho, you'd either need something w/ more juice or a 2nd card like an 8800 / 9800 ($75-100) dedicated to handling Physx.

is 5750 or 5770 godd/ future proof for about 2 years?

5770 or GTX 260

1440x900 is basically 1280x1024 with 30 more pixels which is a neglible difference. A 4870, 4890, or 5770 will all handle it fine. The 5770 will have the least problems with power and supports DirectX 11 so it will probably last longer.

The HD5750 will be an upgrade from what you have, but the problem is, it isn't much of one. Just get the 5770 -- you don't want to upgrade sooner because your, "trying to save money," ended up hurting you, do you?

you do have a point because if i save $40 now i will prob wait one year because its not good enough and spend another 150-200 when i coulda just spent that $40 and kept it for 2 years, so its basically between the 4870 and 5770, if i see a brand new 4890 for around 160 give or take without mail in rebate i would just buy that, but seeing has how thats very unlikely i guess basically it comes down to this, the 4870 is equal to or a little bit better in performance over 5770, in the next 1 -2 years will there be enough of a reason to go to direct x 11? meaining would i regret not buying the 5770?, Btw i dont buy alot of games, , but i am looking forward to sc2( which im not 100% i will buy it) and diablo 3 ( i have a feeling diablo 3 will be my first dx11 title and that wont come out for a few years? just guessing), and im not sure about the next crysis. so in a direct x 11 game will the 5770 blow away the 4870, having better looking graphics, and higher frames?, or will there be maybe a slight or no fps/graphical advantage? im asking this because of tessalation but i dont know if tesselation is a factor at higher quality settings.

basically is there going to be a huge difference of performance and graphics in dx 11, i dont mind a slight disadvantage seening as how dx 10 barley looked better than dx 9. because if a 4870 basically has the same fps on the same settings as a 5770 (except for dx11 on) theres no point. i could just save the extra money for a better cpu or more ram.

so is dx11 worth the upgrade from all the screenshots im looking at, theres not a big difference just a bit better shading

well with that information i take it as games are more optimized for dx11 the 5770 will beat the 4870 in a few months. so now i have to debate whether to go 5750 or 5770 because i really just want my graphics to look better than xbox 360 i dont really need the absolute highest quality.

If you're willing to buy the 4890, then buy the 5770.

Simple as that.
