I wanted to address a topic today, which corresponds with this thread.
Adequacy.
I think now I finally realize, why my friend with the Athlon II X4 640 (3.0Ghz) rig, still uses it. It's completely adequate for his current needs. He does want to do some gaming, and some streaming, he claims, but for what he's using it for right now (web browsing and watching Twitch), combined with an entry-level Fermi GPU, Win7 64-bit, and most importantly, a 120GB MLC SSD (Crucial M500), it's completely usable. (I hooked him up with 4x4GB of cheap DDR2 RAM from a China vendor on ebay some time ago. We had to try two sets before we got one that worked, but his current set seems to be working well, and 16GB of RAM on an Athlon II X4 certainly doesn't hurt.)
I was pleasantly surprised at its performance using it the other day, when I went over to replace his chassis rear fan. He had called me a few days ago, very concerned, that his PC was making loud noises.
Of course, I figured, has to be mechanical, it's either the chassis fan, the CPU fan, or the HDD. So I told him to get a plastic ball-point pen or something, and to take off the side, while it was running, and stick the pen in the chassis fan, and the CPU fan, and see if the noise stopped.
Well, it turned out to the rear chassis fan right away. When I got there yesterday to replace it, he had actually cleaned it, and claimed that it no longer made noise, but when I picked the PC up and started it on my lap, the fan was rattling and making noise. So I figured that it should be replaced. It had like a thick, like 1/4-1/3in. layer of black dust, between the grate, and the fan. Most of the holes in the grate were plugged up. Thankfully, he runs his CPU at stock, so there wasn't really much of a thermal issue, but some airflow would probably help. Then again, there was a thick layer of dust on everything. Going to have to get a few Can'O'Air's and get rid of the dust. Maybe a small hand-held vacuum.
Anyways, I brought with me both an 80mm as well as a 120mm Rosewill case fan. Turned out his was an 80mm. Probably the original fan, from when I sold him the case with a PC, like 10 years ago (!). Pretty amazing that the fan lasted as long as it did, under the conditions that it did. Anyways, I replaced it, now it's running nice and quiet.
But I think that I'll talk to him about replacing the CPU cooler too, since that was getting caked on with dust and hairballs and stuff. Maybe just needs a good cleaning.
Edit: Or maybe even a CPU upgrade, to a Phenom II X6 1055T, with the L3 cache and 6C. I bought one, maybe 6 months ago, thinking of upgrading his rig (and keeping the 16GB of DDR2 installed), it was a little pricey sourcing a new one (ebay), around $100. (Yeah, I know, you can get a 6C/12T Ryzen R5 1600 for the same price in-store at Microcenter. But then he would have to drop $110 on 16GB of DDR4, to maintain his RAM amount with the new rig, and have to get a mobo too. I do want to do that for him eventually, but right now, I figure extending the life of his current system is not such a bad idea.) Yes, he would be paying me back for whatever parts I put in.
Edit: Oh, I forgot to mention, I was going to hook my friend up with an RX 560 2GB GDDR5 (Sapphire) card, to replace his GT610 card, as well as the upgrade to a Phenom II X6 1055T, then maybe he actually could game + stream on his PC, if he really wanted to. (Does ReLive work with an RX 560 2GB card?)
Edit: OTOH, I could give him the Sapphire 4GB RX 470 GDDR5 DVI-D card, which would most definitely allow for ReLive (unless they have a software lock-out on the "mining card" models, hmm). But I think that has an 8-pin PCI-E power socket, and his TR2-430 (new model, 5-year warranty), only has a 6-pin. Although, I did pick up some 6-pin to dual 6+2-pin power adapters. Would probably work OK.
Yeah, I think a Phenom II X6 1055T (3.0Ghz base clock, 6C), 16GB DDR2-800, RX 470 4GB (DVI-D, only good for 1080P, but his monitor is only 1080P right now), SSD, 500GB WD Black HDD, would make a decent lower-end gaming/streaming rig. Might try to talk him into a 500GB Crucial MX500 SSD too. Could clone his existing SSD.
Edit: Or maybe, I have a GT 1030 GDDR5 (refurb, pristine), and a GTX 1060 3GB GDDR5 (refurb, pristine) card that could go in his system. Neither of those require a PCI-E 8-pin power connector like the RX 470 4GB DVI-D card does. Would a GTX 1060 3GB be too much GPU for an Athlon II X4 640 (3.0Ghz)? What about a Phenom II X6 1055T (3.0Ghz base)?
