Not a bloody clue...

I'm looking for a SFF GPU for an oldish i5 PC I've got, has to be SFF and if it could be 'self powered' it would be easier, but I can always ask a techie in work to install it for me. PC is i5 with 8GB of RAM, but I could make it 16GB if I need to.

Looking at a Nvidia GTX 750ti 2GB OR a GT730 which is obviously lower spec BUT it's 4GB - quick rule of thumb, does memory trump model number?

It's for GTA V and Minecraft.

No, memory doesn't trump model number.

It CAN help frame rates at high resolution but memory is far from the be all and end all of graphics card performance.

I find that sites like:

Can give you a decent comparison for performance. These are of course generic numbers and may not be applicable to your setup, but loking at the two models you've mentioned, I'd pick the 750Ti every time.

Numbering/naming schemes differ from manufacturer to manufacturer.

In general, Nvidia uses the first digit as the family (here '7'), so both the cards are the same generation. Probably. There are exceptions*.

Then:

GTX >> GT
Ti >> not Ti
750 >> 730

* in some cases, lower numbered cards can be the same GPU from an earlier generation, repackaged as the lower end of the current generation, often with more memory slapped on.

Also note that the performance of cars can overlap between generations - a notional 'GTX690Ti' could well be a much higher performing card than perhaps a 'GT720'.

Indeed, your example '690' would likely be a higher performing card than anything up to a 780, under most circumstances. The gulf between the tiers of card tends to be far far greater than that between the generations.

In relation to memory, VRAM requirements increase in relation to resolution and graphical settings. Lower powered cards are likely to run out of GPU power before they run into memory limitations i.e. the card won't be capable of running at a satisfactory frame rate at higher resolutions with all the graphical bells & whistles irrespective of the VRAM available. Of the two, 750 Ti all the way.

Go on there and pick the recommend one for your budget. Good site with plenty of guides/reviews.

One thing to bear in mind is if your power supply is good enough. Most half decent +500w PSU's can handle most low-mid end graphics cards.

Oh and 8Gb of RAM is more than enough to handle GTA V.

It's a great game on PC like!

You haven't said what your budget is.

You can get a 970 in SFF but it'll cost about £260

Thanks for all the advice - will order a GTX 750Ti next week. They don't have any 9 series cards.

Didn't really have a budget in mind "less than the amount that would make my boss hit the roof if I ordered it in work" there's a smaller model on TechData it's £80 or so (plus vat).

Bought the game this morning, few hours of swapping discs (all 7 of them!) and now 2 hours of downloading it.... Hope it's good, my current GPU is a GT 620 1GB which I'm told should give me console-esq graphics, but he didn't say PS3 or 4.

I've got a new CAD workstation coming into work soon - twin 10 core Xeon, 64GB RAM and a 4GB Invidia quadro K4200 - might see how it runs on that wink
