Hello, I'm looking for a Radeon HD video card to upgrade an older Thinkcentre (SFF) with a PCI-e x1 slot.
I've come across several video adapters as I upgraded my 32" lcd monitor to a high resolution. Is one reason for the graphics card upgrade. (The built-in graphics has 128mb memory using another 128mb of system memory for a total 256 mb)
However I'm told that a Radeon HD might or won't work with PCD-e x1?
Two cards I'm currently looking at.
Sapphire Technology AMD Radeon HD 6770 1GB GDDR5 PCI-E HDMI/DVI-I/DP Video Card
LENOVO FRU 03T7092 AMD RADEON HD7450 1GB GDDR3 PCI-E Video Card - DP/DPI
I'm mainly looking for a faster card with more memory to connect to the new 32" Nec monitor with digital hdmi and dvi-d inputs.
For some video adapters I've come across minimum PC PSU power requirement of 300 watts and 350 watts. My Thinkcentre uses a 250 watt power supply
Any video adapter would need to have drivers for Windows Vista x64.
