Pci lane issue

[sourav_1988]

hello friends. i already started a thread on graphics card. and there i came to know about the pci lane compatibility. first of all, my specification is-

Processor: E5800
RAM: 3GB
Motherboard: G41-M7
Present Graphics card: GT 520
PSU: 300W
Budget: Rupees 10000

and i want to play games on ultra settings.

now this is what mentioned in the motherboard manual.

PEX16_1: PCI-Express x16 Slot
- PCI-Express 1.0a compliant.
- Maximum theoretical realized bandwidth of 4GB/s simultaneously per
direction, for an aggregate of 8GB/s totally.
- PCI-Express supports a raw bit-rate of 2.5Gb/s on the data pins.
- 2X bandwidth over the traditional PCI architecture.

if i buy pci-express 3.0 card or 2.0 card or even 4.0 would they be compatible with my motherboard ??? since the slot itself is 1.0a compliant.


thanks in advance.

just to add..gt 520 has pci 2.0 bus interface and presently it's working fine with my mobo.

Everything when it comes to PCI-E is backwards compatible. You're probably not going to be able to play games on ultra settings with an E5800 and 3GB's of RAM.

I think he should play safe and not go with a PCI-E V3.0 card.But if a 2.0 card is working,then a 2.1 card should probably work.

 

[sourav_1988]

now which one to buy considering the solution. still i am very much confused.

If you want performance above the 6850(you talked about getting the 7850),you can get this combo if you plan on keeping your GPU when you upgrade your processor and monitor(basically when you upgrade your pc)-

It's PCI-E V2.0 so it should be fine as you are now running a v2.0 card(the GT 520).I know it's over-budget and overkill,but you would already be stretching your budget so,at least,it's cheaper than the 7850.
For PSU,

However,if that is out of budget,get this -

and the same PSU.This is also PCI-E v2.0.See,the 6850 would be more than sufficient for 1024x768 and if you buy a higher powered card,the difference won't be noticeable if you do not plan on upgrading your processor and monitor.However,if you do plan on doing so in the near future,get the 6870.Hope this helps.

so, according to you if i buy nvidia product then i wl be on safe side.. is it?

 

[GreenDutchAlien]

Yes, but NVidia has nothing worthwhile in the lower priced segment, you shouldn't get lower than the GTX560. ( ti or non ti )

The Sapphire 6870 2.0 from absxiith should work also, though i never heard of a 6870 2.0 before. ( doesn't say much, lots of cards i never heard from )

The 2.1 and 3.0 version can give problems with a 1.0 mobo but those cases are few.

Were i live it's not a problem, when i buy a card and it won't work i can always send it back and get different one without even mentioning the reason ( within 2 weeks ), i have a feeling that that might not be the case where you live, so don't know if it's smart to take the risk.

Don't forget ; for all these cards ( except the 6670/7750 you'll need anew power supply.

You don't need 600W though, 500 is enough.

yeas...i think i am narrowing my target now. .. so now it's between 6870 vs gtx 560 ti. because they almost priced same. thanks for the replies. just nid a lil more help. thanks in advance.

 

[sourav_1988]

one more thing that i found hd 6870 is pci 2.1 compatible.

Better go for the 560 then, specially if prices are about the same, better card and 2.0.
