Non-Gaming APU PC upgrade question

normally, I never second guess the advice I give to a family member on any kind of computer advice. recently, I helped my brother replace his laptop and with an HTPC running an A8 black edition APU, with 8 gigs of ram and an SSD (transferred from his laptop).

recently his computer had minor issues, and I was worried his computer was being taxed too much with the APU pulling double duty like it does when there is no dedicated GPU. I told my brother two things he could do would be to upgrade to win 8.1 and to grab a low profile GPU.

we ended up picking out a HD 5450 1 GB, because my brother is not a gamer. its currently intstalled in his system right now. my brothers computer is password locked so I couldn't check to see if the 5450 helped or hurt, due to the fact that the GPU part of the A8 is stronger than the 5450. did I give my brother bad advice on the card to go with?

I would've told him to go GT 640 or 6670, but he isn't a gamer so I felt such an upgrade would be wasted on him.

yeah... the 5450 is slower then the apu's own igpu. you didn't fix the problem, that much is sure. what's he doing that makes you think he's taxing the gpu? what's happening?

well his computer was running slowly and I had checked it atleast three times, running virus scans, and even doing completely reinstalling windows. his computer just always seemed to lag like crazy. so I figured it had something to do with the fact the APU was eating a lot of resources, cause I can only imagine how much ram that thing uses (and my brothers PC used a good bit more than my Phenom II build with a 6670). I figured giving it its own dedicated GPU with a good solid amount of RAM would take some stress away from the CPU and maybe fix whatever was causing his PC to lag. he told me the PC runs faster now, but I haven't seen it action for myself

well... was he using the stock heatsink... cause what you're describing sounds like overheating. You see, the cpu part of that computer is roughly equal to a phII... he's got a lot of horses under the hood... it's a quad core... nothing outside a game should challange a phII with a 6670 gpu (which is roughly what he's got)... so if all he's doing is web surfing or watching videos and having issues then there is something else happening. he probably is overheating and temp throttling... (atleast that would be the first place i would look). those quad core APUs run rather hot.

well he is using a stock heatsink, and overheating was something I kept in mind when telling him ti get the 5450. I would imagine the APU would run at a lower temp if the graphics core isn't active, thus improving his experience, even if only mildly. I downloaded coretemp, but I don't trust it seeing as there currently isn't a program that accurately reads the temps of the newer AMD CPUs.
