Sudden framedrops. (Advice needed)

[SO•Marty]

A kick, I have been investigating a bit more in this.
At the time I asked this question I wasnt using LFSLazy, I now do and I noticed something.

When LFS is running, CPU and RAM seem fine (CPU is used for about 49/50% constantly, RAM is around 4GB (of 8GB, so about 50% as well). But the GPU is constantly maxing out, at 98-100%, and I notice a lot of framedrops happen when I change views (during towing/medding it can be useful), or when I stand still in SZ or at a pitstop. Especially the view changing asks much of the videocard I imagine, and I can imagine it cant handle it at that moment and stalls.

I think my videocard might be dying, is it possible to upgrade this and the issue might be resolved?
The advantage of an older pc, is that upgrades are relatively cheap, but I am afraid if I do that the cooling/motherboard and other ancillaries have to be upgraded as well, so it would be come too expensive and it would be better to buy an entire new pc.

I might be thinking of this videocard: https://www.geforce.com/hardware/desktop...rce-gt-710 , the GT-710, but maybe its best not to invest in an 8 year old pc lol.

I hope you guys can shine a light on it.
