I have no idea. We don't have enough data on the subject to properly calculate predicted performance.
The data we do have would seem to suggest 2x or 2.5x being the max for the DDR3 variant (depending on the game) while 3x or 4x should be easy to do on the GDDR5 variant. But I have to make a lot of assumptions to reach that conclusion and would never confidently support my own predictions.

If discounts allow it.. then yes, I'll get the gddr5 variant.
Would the gddr5 variant of the gt 440 be any good?

(If not, then I'll just get the ddr3 version of the gts 450.)

I think I already wrote in this thread,but build where gpu is 440 or 450 is not good $500 build. Its crappy $500 build

GTS 450 shader throughput: 192 (number of SPs) * 1566 MHz (shader clock rate) * 2 (number of single precision shader ops a SP can complete in one clock cycle) = 601.34 GF/s
GTS 450 texture fillrate: 32 (number of TMUs) * 783 MHz (core clock rate) = 25.01 GT/s
GTS 450 pixel fillrate: 16 (number of ROPs) * 783 MHz (core clock rate) = 12.53 GP/s
GTS 450 video memory bandwidth: 128 bits (buswidth) / 8 (number of bits per byte) * 3608 MHz (memory clock rate) = 57.73 GB/s
The DDR3 variant of the GTS 450 has an 1800 MHz memory clock rate which gives it half the video memory bandwidth (28.8 GB/s)
GT 440 shader throughput: 96 * 1620 MHz * 2 = 311.04 GF/s (half the shader throughput of a GTS 450)
GT 440 texture fillrate: 16 * 810 MHz = 12.96 GT/s (half the texture fillrate of the GTS 450)
GT 440 pixel fillrate: 4 * 810 MHz = 3.24 GP/s (about 1/4th the pixel fillrate of a GTS 450)
GT 440 video memory bandwidth: 128 / 8 * 3200 MHz = 51.2 GB/s (the GDDR5 GT 440 has about the same memory bandwidth as the GDDR5 GTS 450 and double the memory bandwidth of the DDR3 GTS 450)
Both chips use the same microarchitecture so their specs can be directly compared. Most PC games are bottlenecked by the shader throughput and/or pixel fillrate. So as far as PC games are concerned the GTS 450 will be 2-4 times as fast as the GT 440 depending on the game. Dolphin is more likely to be limited by memory bandwidth.
You should try and do whatever it takes to get the GDDR5 GTS 450.

Well, is this a good "whatever"?
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371033
Despite it being 380 watts, it can apparently power a gtx 460.
(Which requires a higher footprint then a 450.)
Because either h61 or that psu.
Unless you can recommend otherwise?
And of course, this:

Anything higher, and I hit the danger zone.

Behold: http://extreme.outervision.com/psucalculatorlite.jsp
According to that 380 watts is enough but BARELY. At full load the system will use 346 watts without any fans (I don't know what case fans you have, also I put in the 3.4GHz turbo overclock when I did the calculations). I would not recommend skimping on the PSU since you will probably not be able to carry it over to your next system (not very future proof). I would recommend getting an H61 board instead.

And the 430?
(Because I can get that too...)

So I made a new thread for this because I'm an idiot and didn't look into this thread first. Is there a way I can delete my thread since I'm attaching my question below.
Quote:Would this machine be able to handle dolphin
http://www.tigerdirect.ca/applications/S...u=B69-0425
3.1 Dual-Core (Could probably overclock it to make it better for dolphin)
12GB DDR3
1TB HDD
M4A88T-M Motherboard
450 WATT power supply
$350 seems like a good price for that PC so I was wondering if it would be able to handle dolphin in HD for most games. Sure I would need to order a new video card (ATI Radeon HD4250 is built into motherboard) but other than that would this PC be alright.
PS: If so, looking for suggestions on a fairly cheap video card to order. If not, any cheap alternatives to this PC I should look into?

Same answer.
