What's a good GPU for a Haswell G3258 (dual-core) @ 4.2Ghz? Something not too expensive, and doesn't take too many CPU cycles (since there aren't that many with a dual-core)?
Or is this all a pointless exercise, for a dual-core in 2020 for gaming, and I should just stick with something for display-output only (4K UHD capable)?
Right now, I have an MSI 1GB GDDR5 (I think 128-bit) GT 740 (Kepler) in there. There is a PCI-E 6+2 power available, but unused by the current card.
I could drop in an RX 580, RX 470, and I sold someone my RX 570, that has to go out soon. But doesn't the AMD cards have a higher driver overhead than NV?
I'm not necessarily looking at new cards, only if they're a bargain. CPU was used from ebay, mobo was factory refurb from Newegg, PSU is new Corsair CX450, case is used, have a Gammaxx 400 cooler on there (should be good to max out whatever overclock CPU+board card muster. I haven't completely game-stress-tested the 4.2Ghz OC yet.)
Was contemplating a GTX 750 or GTX 750 ti (Chineseum edition) from Newegg 3rd-party sellers, then I saw some under-$100 RX 550 4GB and RX 560 4GB.
Then again, I can even get a brand-new RX 570 4GB from ASRock for $100-110 @ Newegg. For the money, that's probably the best deal, more or less, but then I worry about the CPU overhead on the drivers, and it seemed from what I read that games performed better (less stuttering) with this CPU, in GPU-limited situations, rather than CPU-limited.
I probably should have just gotten a 4670K or something, and maybe I still will, but the G3258 was $13 + tax, it seemed like a no-brainer to get this system up and running. I only have 2x2GB DDR3 in there now, too, which is a bit too little for modern gaming, in fact, even a 4GB card like the RX 550/560/570 probably won't work with only 4GB of system RAM anyways, so probably I'm best off with a 1GB or possible 2GB card like I have in there already, and just accept that this sort of rig with only a dual-core (even overclocked past 4Ghz), and only 4GB of DDR3, won't be playing most "modern" titles. It's barely-capable as a browser-box as it is. I guess that it would play Facebook games for some Grandma somewhere.
Would it be an improvement over an FM1 quad-core APU, that's a quad-core @ 2.1Ghz max? Dual-core Haswell @ 4.2Ghz? It might seem snappier for browsing, with the better ST performance. Also, the FM1 iGPU is pretty limited these days as far as driver support and updates go, in Win7 64-bit and especially Win10 64-bit.
I think that the dual-core Haswell w/GT 740 would be a "win" there. Maybe I'll approach that person and offer it to them.
Edit: Actually, that person's FM1 rig, that I supplied the parts for, but didn't build, has 2x4GB DDR3 in it. If I were to give them this rig, I could swap the RAM, and put 8GB into the Haswell rig, and then, possibly drop in my slightly-used (mining) RX 470 w/DVI-D output (only). That might make it pretty decently-capable, and they would be able to watch advanced YouTube with the VP9 decode (I know, I know, hybrid on Polaris).
Or maybe I should forget about the Haswell rig, and just give them my Ryzen APU 2400G rig, and call it a day.
Or leave this person alone, just because I have spare computers, doesn't mean that they want to upgrade. Although, I should point out that Windows 7 64-bit is no longer supported for updates.
