Upgrading my video card for Far Cry 3 (help)

#1 Posted by S0mewh4tD4m4ged (346 posts) -

I am looking for a ~$200 video card upgrade for Far Cry 3. I have a few questions and concerns before upgrading. I currently only have a PCI-E 1.0 slot and I want to purchase a Radeon 7850 or a 7870. I have read multiple threads on performance issues and compatibility with PCI-E 3.0 cards in 1.0 slots but the answers vary.

There should be no compatibility issues. There may be some issues with cards that have the older 1.0a specification but 1.1 should be fine. As for performance, it would not be noticeable...
you will see a performance drop of less than 1%.
You should be able to put a PCIe 3.0 card in a PCIe 1.0 (they are supposed to be backward compatible) slot but your performance (okay, the graphics card's performance) will not be great... actually, it may not even be good. But, when you do your upgrade, (provided your new CPU and mobo support PCIe3.0), you'll be sitting pretty
It will work. PCI-E is backwards compatible. No idea about how worse the performance will be compared to a 3.0 slot but I doubt it will be by much.

I have an older 2008 self built pc. I have read that your cpu has to be compatible with video card which doesn't make sense to me. I don't want to purchase a card that won't give me much of a performance increase. I also am not willing to buy a whole new rig when I am mainly a console gamer and with so many rumors of next gen only a year away. Could someone suggest a video card for around $200 and let me know if a 3.0 card will work with my current setup?

My Rig (yes I know its dated)

Processor: Intel Core 2 Quad Q9300 2.5GHz

Memory: G.SKILL 4GB (4 x 1GB) 240-Pin DDR2 800

Video Card: EVGA 768-P2-N835-AR GeForce 8800GTX 768MB

Motherboard: EVGA 680i SLI

Help?

You probably read that your CPU might bottleneck your video card; this means that a GTX 680 paired with... well, with your processor would not perform as well as it would if it were paired with, say, an i5 3570K.

You can put a PCIe 3.0 card into a PCIe 1.0 slot and it will work fine, but again you won't be getting the same performance out of it as you would if you had a better computer.

Personally? I suggest buying a HD 7850 to hold you over until you can save up enough money for a brand new rig. And you can use the 7850 in the new rig, anyway, so a computer won't cost you as much then and the 7850, when put in a new rig, will perform much better.

@S0mewh4tD4m4ged: Will it work? Should. Haven't tried it myself but PCI-E is backwards compatible through the whole range. As correctly points out a 7850 is in line with the rest of your system and will still scale well when you move it into better hardware. But will it be a dramatic increase in performance? Well, it'll be held back by the rest of your system but it should do better then your current GPU by a decent margin, assuming that the GPU is the current bottleneck.

I agree that you should go with the 7850 for now until you're ready to upgrade the mobo and cpu.
