Breathe new life into old PC Specialist PC.

Hi,

One of our faithful desktops bought from PC Specialist in 2013 is in need of a refresh. Sorry for the static spec but it's way too old for me to link to anything.

Case ANTEC QUIET COMPUTING™ PERFORMANCE P280 CASE link
CPU AMD FX-8350 Eight Core CPU (4.00GHz/8MB CACHE/AM3+) link
(Vishera(
Motherboard ASUS® M5A99X EVO R2.0 (DDR3, USB3.0, 6Gb/s,CrossFireX/SLI) link specs BIOS
Has UEFI BIOS. GPT is required for UEFI motherboards
RAM 32GB SAMSUNG DUAL-DDR3 1333MHz (4 X 8GB)
Graphics AMD FIREPRO™ V4900 PRO GRAPHICS - 1GB, EYEFINITY, DVI x 1, DP x 2 Link
1st Hard Disk 180GB INTEL® 520 SERIES SSD, SATA 6 Gb/s (upto 550MB/sR | 520MB/sW)
2nd Hard Disk 180GB INTEL® 520 SERIES SSD, SATA 6 Gb/s (upto 550MB/sR | 520MB/sW)

Power Supply 450W Quiet 80 PLUS Dual Rail PSU + 120mm Case Fan
Cooling Corsair H60 Hydro Series High Performance CPU Cooler (£59)
Sound Card ONBOARD 8 CHANNEL (7.1) HIGH DEF AUDIO (AS STANDARD)

This dual-boots windows 10 and Ubuntu 20.04 and is mostly used for CAD and office work, plus it runs a few virtual machines when in Ubuntu (hence the stack of RAM). No gaming. It's connected to 2x QHD screens.

It is a brilliant machine and that Antec case is so well built, much better that our later purchases.
I'd really appreciate some suggestions for the following:

New video card. This machine now lags running CAD so it needs a better video card. Nothing amazing, just more on-board memory, 2x DP connectors and as quiet as possible.
The cooler is dying. It's done quite well for 7 years, but too often now the BIOS reports a CPU 'fan error' for the pump. Will probably replace like-for like.

Can we upgrade the CPU any? Sorry but we don't have in-house knowledge of what works with what, though we would be able to assemble. I imagine CPU / Motherboard upgrade would get quite pricey, but might consider it.

Thanks!
