Is a GTX 660M worth an extra £75, over the GT 650M?

As post states, is it worth it? I'm currently building a laptop for gaming and photo editing on PCSpecialist.co.uk, and I have the choice between a 650M, or a 660M. I remember reading somewhere the 660M is quite a good increase, but have seen multiple benchmarks which contradict some what.

PassMark Software - Video Card Benchmarks - Video Card Look Up - puts it 20% ahead

where as this benchmark doesn't put so much between them:
Mobile Graphics Cards - Benchmark List - Notebookcheck.net Tech

Thanks in advance for any responses,

Absolutely.

 

75£ is a definitely worth upgrade. Especially when you check the price to upgrade to a higher tier..

 

You will usually see varying results, because the benchmarks are established under different test machines. Comparisons aside, and going more off the technical specs of each card to determine their price to performance ratio, the 660m is more capable,but it's up to you whether it's worth the extra £75 difference (which isn't bad at all, really). It boils down to what you will be doing. Heavy gaming or 3D rendering, and if you have it to spare? Then go for it. Not simply for bragging rights, but because you will be more up to date, at the very least, and yes, you will have a more powerful GPU.

But if £75 is a stretch for your budget, and the difference seems negligible enough to you, then save that money and upgrade something else or use it to purchase an accessory to enhance your experience with the laptop.

 

If they're both GDDR5? I vote no.

there's a link to what I was building. It just says "DDR5", rather than GDDR5.

PCSPECIALIST - Custom PCs, Custom Computers, Custom PC, Desktop PC, Custom Built Computers, Gaming PC - is the alternative with the 650M, also says DDR rather than GDDR5.

In regards to other comments, I am a gamer, and this is to replace my 2 year old PC which houses a GTX 460, as I'm attempting to downsize. So the idea for me would be to get the most out of this graphically in games, which'll last me the longest before my laptop stops being able to run games smoothly.

 

Like Kevin says, if they are both GDDR5, I`d pick GT650M if money is short. GT650M and GTX 660M is the same GPU, the 650M have gotten its clocks down to differentiate them.
So what you can do is get the 650M and overclock it up to 660M. Or flash the VBIOS to the 660M clocks and you don`t have to manually overclock it anymore. You have a GTX 660M.

But if this is a hassle for you, buy the 660M.

EDIT: That 650M have GDDR3. Stay clear and buy the 660M. Its worth the extra £75 for sure

 

I'd go with the 660m for sure as the others have said. Your GPU is what you want to maximize as much as possible as it will be the first component on your system to be bottlenecked in the years to come. Plus from what I understand, the DDR3 version of the 650m is crippled by the slower memory speeds at higher resolutions.

 

Yeah I'm glad you guys helped me notice the 650m is DDR3. So looks like the DDR5 GTX 660M it is for me! Now, let's hope nothing serious comes up in the next few months that I'll need this money for!!

 

As a new 660m owner I can't comment directly on the 650m, but I've been very happy with the 660m thus far... it preforms great, significantly better than the 5870 it is replacing, which surprised me. If gaming is important, which you say it is, I'd definitely go ahead and spend the extra few bucks.

On a different note, if you are open to overclocking, it is possible to overclock the 650m to similar speeds of the 660m, but then of course you can always also overclock the 660m when needed... from everything I've read they are pretty similar and just binned differently.

EDIT: just saw posted above the 650 you are looking at is ddr3, as others said definitely go 660m in this case, enjoy!
