I'm using a 64bit windows xp.
And don't worry about the mac thing.

That's not how it works. A 32-bit OS has enough address spaces that total 4GB. Even with a 1GB video card he would still have enough address space for 3GB of RAM, which is what he has. There may be a very small loss below that for other computer items that need to map address space, but that would be minuscule at best.Stubbee wrote:

You mean minuscule at WORST

there is about 500MB worth of reserved I/O besides the video card. Keyboard, mouse, DMA, PCIe, ethernet, modem, sound, floppy drive, HD, RAID and quite a few other system resources require I/O addresses.
I have 4GB installed but with a 256MB video card i had access to 3.25 GB.
I upgrade to a 512MB video card and now my system has access to 3.0 GB.

No, since I don't know, but I know you're wrong.
ah you don't know but you know i am wrong.
Either prove I am wrong or GTFO

I think you're up in the night on how much room is required for I/O and other functions. I ran an XP system with a 512MB video card (8800GT) and 4GB of RAM, and still managed to have 3.15GB of usable RAM, and that included dual NICs, an X-fi sound card, and a 2-port RAID controller card, not to mention whatever else the system must have running.
@dung
ok if you had 3.15GB of usable RAM with a 512 MB video card and if you grab 1 GB card which is .5 GB more where do you think your system is going to find the I/O for it?
3.15-0.5 leaves you with 2.65GB usable RAM
while CammRobb is out shopping for Vagisil you can read any of the gazillion links here
4GB limitation 32 bit OS
some systems can use PAE but from everything I have read about it, it is a pain in the ass.

I'd type my pc specs out all fancy again but teh mods would remove it. Again.

Geeze Stubb, if you're so adamant about being right and proving everyone wrong how about you go and look for the answer on a proper tech website? Quit talking about your e-penis and just slap the bitch on the table and show what's what. Or keep it in your pants, tucked between your legs. Fuck man, you guys are ruining a perfectly good thread with this childish BS.

It can be around 500MBs worth of IO address space. It depends how much hardware you've got.Agent_Dung_Bomb wrote:

As far as I'm aware the memory on video cards is not discretely mapped though, so all this bollocks he's spouting about a 1GB video card taking up 1GB of address space is total bullshit.

Old Card = Slow... Use more space than You think.
New Card = Fast! Use about what it say it does on tin.
Duh?
Dont believe everything the stats tell you. Tool.

go with the 5770 for that price range.

I realize what is installed can make a difference. That's why I noted that I had a substantial amount of additional hardware installed, beyond that stuff integrated into the motherboard, and that used ~350MB, and that is probably an excess. As far as the video card, I think it is discretely mapped into that address space, as even in 2D mode when only a fraction of video memory is used the available RAM appears to be missing.Bertster7 wrote:

As for the OP, I see the 5770 as a very nice performing mid-range budget card. I've got a 4850 and 4890 and couldn't be happier with the performance that both cards have given me. I've had very little in the way of driver issues. If I had any game glitches they were minor and I found that getting the latest drivers resolved the issue.
However, as noted, you are going to pay a premium for the version that is Mac compatible; and you will find that for just about everything relating to the Mac.

5770 slots nicely inbetween the 4870 and the 4890 for performance. Neither of the aforementioned do DX 11 though.
I've checked this now. Video RAM is definitely not discretely mapped. A video card takes up the same amount of address space as any other device using the same slot. It is just the mapping of the number of lanes to the card.Agent_Dung_Bomb wrote:
