Hello, I have yet to purchase MSI GAMING N750Ti TF 2GD5/OC G-SYNC Support GeForce GTX 750 Ti 2GB 128-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card from new egg, i have been speaking to someone over on HP Forums.. I’m new to upgrading and I don’t really understand it all that well. I am using a HP Pavilion HPE h8-1070uk Desktop PC. I just wanted to double check that the card would be compatible with my motherboard if i were to switch the card to legacy mode? Also does legacy mode work with all older motherboards? My motherboard is IPISB-CH2 (Chicago).Hope you can help. Many Thanks.
