Differences

Reasons to consider the
Nvidia GeForce GTX 750 Ti


Higher clock speed 1,020 MHz vs 900 MHz Around 15% higher clock speed
Better passmark score 3,666 vs 1,928 More than 90% better passmark score
Better 3DMark vantage graphics score 20,401 vs 9,923 More than 2x better 3DMark vantage graphics score
Higher effective memory clock speed 5,400 MHz vs 4,104 MHz More than 30% higher effective memory clock speed
More memory 2,048 MB vs 1,024 MB 2x more memory
Higher texture rate 82.64 GTexel/s vs 28.8 GTexel/s More than 2.8x higher texture rate
Better floating-point performance 1,728 GFLOPS vs 691.2 GFLOPS Around 2.5x better floating-point performance
Better 3DMark06 score 5,378 vs 2,272 More than 2.2x better 3DMark06 score
Higher pixel rate 16.32 GPixel/s vs 7.2 GPixel/s More than 2.2x higher pixel rate
Significantly higher memory clock speed 1,502 MHz vs 1,026 MHz More than 45% higher memory clock speed
More shading units 640 vs 192 448 more shading units
Better passmark direct compute score 1,669 vs 803 More than 2x better passmark direct compute score


Reasons to consider the
Nvidia GeForce GTX 550 Ti

More render output processors 24 vs 16 8 more render output processors
Wider memory bus 192 bit vs 128 bit 50% wider memory bus

Might be a stupid question, but I'm overly cautious...

I'm not sure I'm following exactly. Do you have a 550 Ti and now consider getting a 750 Ti or are you looking at a replacement for the GT 420 from your other thread?

Anyway...
You can look at Tom's GPU hierarchy chart to get an indication of where a GPU lies performance wise. Tom's reviews can be a bit biased sometimes but the hierarchy charts are useful as long as you compare AMD to AMD and Nvidia to Nvidia.

Tom's rule of thumb is that to get a notable performance increase, you need to buy at least three tiers higher. The 750 Ti is 4 tiers higher than the 550 Ti, so the improvement should be worthwhile.

Remember, it's not the width of the bus how you use the bandwidth

So upgrading from my 560 TI to http://www.takealot.com/gigabyte-nvidia-geforce-gtx750-gddr5-pci-e-3-0-graphics-2gb/PLID28732481 would be worth it ? seems like a good price

Doesn't really look like it, hey. The GTX 750 Ti you linked to is only one tier higher than the 560 Ti so you won't have a big boost in performance. There are other things to consider as well like DirectX versions.

Remember that those charts are just a guideline. Read a few reviews and preferably reviews where the cards you are looking at are compared to each other.

Yea just saw the price and thought it would be worth it, If im upgrading i usually like to do it properly, so will get something that is a major upgrade instead, want to get my SSD and new graphics card together probably.

Jumping to a GTX760/Radeon R9 270X would be the ideal upgrade for you, actually. That way you're not limited much by memory bandwidth, which is the achilles' heel of the GTX550 Ti.

I would wait until the end of November to upgrade though. Maxwell launches in late September/mid October and then you'll have a chance to pick up some cheaper GPUs once the launch is underway.

..........

Sorry for the confusion. The GT420 is my brothers GPU. I've got a GTX 550 ti. Thought I want/need to upgrade after I got takealot's email this morning, but I'll wait a bit like Wesley suggested
